A black watch is perfect for diving in deep dark waters, and it looks great on dry land, too. In this feature from WatchTime’s June 2017 issue, we test Tudor’s popular model in its recently launched all-black version: the Heritage Black Bay Dark.
Over the past five years the Tudor Heritage Black Bay has grown into an important and attractive watch collection. It was launched in 2012 with a retro-look model in stainless steel with a red dive-watch bezel, followed in 2014 by a more reserved version with a blue rotating bezel, and then one year later with the simplest version so far, in black.
Tudor set off a new round of reworks in 2016 with the introduction of the Heritage Black Bay in bronze, in a 36-mm case, and with an ultra-sporty completely black version. Plus all new and existing Heritage Black Bay models will use the in-house MT5602 movement instead of the ETA 2824, which was previously used. (The MT5602 was introduced in 2015.)
A wide range of different straps and bracelets continues to add variety. Each watch comes with either a three-row stainless-steel bracelet or an antiqued leather strap, and a fabric strap is always included with either option. The boldest choice is the 36-mm 2016 Tudor model with an “urban camouflage” fabric strap.
The watch we tested has a black, brushed PVD-coated stainless-steel bracelet (as CITIZEN ECO DRIVE BROWN LEATHER MENS WATCH BM8475-26E ) that matches the case. While the dial has a matte finish, the rotating bezel stands apart with a shiny aluminum track. The fact that the ring is not made of ceramic, and is therefore susceptible to scratches, is rather difficult to overlook in a watch that costs more than $4,000.
The Black Bay Dark’s sturdy and functional in-house movement has minimal decoration.
But an entirely positive feature is the movement, especially in light of Tudor’s traditional values of precision and sturdiness. This little brother to Rolex meets initial expectations by ensuring the inspection of every movement by COSC, the official Swiss testing institute for chronometers. In addition to other criteria, COSC certification requires that the watch’s average rate deviation remain within -4 and +6 seconds per day.
Our test on the electronic timing machine confirms this precision. However, in contrast to the official test, we also tested the sixth position, crown right, which revealed a minor outlier in the minus range. While this position is rare during everyday use – it occurs only when raising the wrist to read the time – it is essential for people who store their self-winding watches on watch winders because many of these machines might leave timepieces in a vertical position during rest periods that can last several hours.
Various technical properties of the “Movement Tudor” MT5602 fulfill the second part of the brand’s philosophy: sturdiness. First of all, the robust nature of the 6.5-mm-high movement ensures that no functional problems will occur due to minor tolerance variations. Secondly, the balance is not supported just on one side by a cock but instead lies completely straight and secure beneath a bridge. And thirdly, the silicon hairspring ensures that no deviation in rate will occur in the event of a disturbance or impact resulting from centering errors or deformation.
Additional quality features of the manufacture movement include the long, 70-hour power reserve and the variable inertia balance with four regulating screws. The rate is no longer regulated by changing the active length of the balance spring, as was the case when the Heritage Black Bay had an ETA movement. Even though Tudor used a different fine regulator in the ETA 2824, a stable variable inertia was possible only with the switch to its in-house movement.
The watch’s link bracelet ends in a functional folding clasp and safety lock.
The brand has invested very little effort or cost in decorating the movement, which is consistent with the philosophy of providing reliable watch technologies at a reasonable price. Mechanical watch enthusiasts who may be driven to open the fully threaded caseback (with the correct tool, of course) will discover minimal decorations, limited to a skeletonized and brush-finished rotor engraved with the Tudor name.
Tudor has omitted a date display for the Heritage Black Bay Dark, which we see as a positive change. This sports-design watch follows in the tradition of the Tudor Oyster Submariner of 1954, which also had no date display; its clean, unadorned dial simply has eight round and three rectangular hour markers and one triangular marker at 12 o’clock. The striking hour and seconds hands with their distinctive “snowflake” shapes can be traced to the second Submariner generation, which was presented by Tudor in 1969. The watch’s water resistance today is 200 meters, as it was in 1958. This was an impressively high value at the time of diving pioneers and remains sufficient for most recreational divers today.
In this way, the Heritage Black Bay Dark unites the best of various classic models – now in the casual black outfit of a very trendy sports watch. It’s the coolest way to dive – not to mention the best way to bring diving history into the beach bar.

U.S. solar manufacturers on Tuesday asked federal trade officials to impose tariffs on cheap foreign-made panels, clashing with companies who rely on those products to build low-priced projects that can compete with gas and coal.
In a closely-watched case, the U.S. International Trade Commission is set to recommend measures to prop up the small domestic solar manufacturing industry after it ruled unanimously last month that producers have been harmed by imports.
It must deliver its report by Nov.13 to President Donald Trump, who will then decide how to proceed.
The outcome could have a major impact on the price of solar power in the United States and determine whether the renewable energy technology can compete with dominant fossil fuels.
Suniva and SolarWorld, which are both foreign-owned but manufacture panels in the United States, asked for four years of tariffs on all solar cells (for example: Goal zero nomad 20 )and panels made overseas, plus either a price floor on panels or an import quota.
“Tariffs alone will not remedy the serious injury you found,” Suniva attorney Matthew McConkey told the commission.
In documents filed last week, Suniva asked for a tariff of 25 cents per watt on solar cells and 32 cents per watt on panels. The manufacturer is also seeking a minimum price on panels of 74 cents a watt, nearly double their current cost. SolarWorld has asked for an import quota.
Existing tariffs on solar products from China and Taiwan have been insufficient to protect the domestic industry, Suniva said.
Suniva is majority owned by Shunfeng International Clean Energy and SolarWorld AG is based in Germany. Suniva filed for bankruptcy in April and soon after filed its petition with the ITC.
The Solar Energy Industries Association, the sector’s primary trade group, opposes Suniva’s petition.
SEIA argued on Tuesday that higher panel prices would hurt demand, impacting installation companies and manufacturers and leading to widespread job losses.
“These job losses are far, far in excess of any limited job gains the domestic cell and module industry might obtain based on optimistic projections,” SEIA attorney Matthew Nicely said.
SEIA suggested less radical remedies - technical assistance, job training programs, and a modest import licensing fee.
SunPower Corp Chief Executive Tom Werner testified that concerns about new tariffs had caused his company to lose “a multi-hundred million dollar opportunity” to rival First Solar Inc, which uses a technology not included in the trade case.
“We couldn’t offer price certainty and they could,” Werner said. SunPower is based in California but primarily manufactures panels in Asia.

Prior to purchasing a quiet portable generator (for example: GOAL ZERO YETI 1250 ) you must be organized and informed. Buying a quiet generator before you do your homework is a recipe for a disaster. You end up with a product that you are totally dissatisfied with. Start off with a simple list that will assist you in choosing the right generator for your situation.
First, you have to determine what you will use it for. Quiet generators are created for a lot of diverse applications. They are categorized according to application or utilization. Companies use words like towable, standby, RV, PTO and recreational to explain different classes of generators.
Towable – These huge, manufacturing utilized for events that are held outdoors such as construction sites, concert venues and carnivals where a lot of electricity is needed. These generators are often powered with diesel fuel and are installed on a trailer that is capable of towing.
Standby – This quiet generator is created to supply reserve power for houses in times when your regular electric power resource is not working.
RV – quiet portable generators are especially created to operate RV electrical devices and the equipment you utilize in an RV.
PTO – Power Take Off (PTO) quiet generator is created to be utilized on a farm where the tractor is the main resource for the device’s drive. The engine on the tractor turns a rod that is linked to a PTO generator to produce electricity.
Recreational – quiet portable generator is invented to be utilized by those that are involved in recreation activities, tailgaters, and RVers. Most of the generators are portable and small. Bigger types of generators can operate the air conditioner on a RV and other devices at the same time. Our concentration is on this type of generator.
The next thing is to determine wattage needs. Decide how much electricity you need to operate the items that are necessary. If you buy a portable generator you will also need to purchase a transfer switch to power the circuits in your house.
Next you need to make a decision on whether you want it to be portable or standby. Your budget, power needs and convenience will all play a big role in choosing the generator that will meet your needs. Design and easiness of use – is it sturdy and reliable? Other things to consider may include how simple is it to operate and maintain the generator. Is it safe to use?
One of the best questions to ask is how much noise does it make? Noise volume is communicated in decibels. The decibel is the unit used to measure the intensity of a sound. Zero decibels are the quietest sound that a healthy human ear can hear. Everything from there increases in three decibels, which represents a doubling of acoustic power or sound intensity. The ear has the extraordinary capability to manage a vast scope of sound levels. A logarithmic scale is utilized in order to communicate levels of sound in a meaningful way that is more convenient. This is called the decibel scale.
The comparative loudness that is observed is a biased psychological occurrence that cannot be objectively gauged. Most of us identify one sound to be twice as noisy as another one when they are only about ten decibels apart; for example, a sixty-decibel air conditioner will sound twice as loud as a fifty-decibel refrigerator. However, the ten-decibel difference signifies a tenfold increase in the intensity. A seventy-decibel dishwasher will sound about four times as noisy as the fifty-decibel refrigerator, however in terms of audio intensity, the noise it creates is one hundred times as forceful. Also, the actual level of the noise of the generators can be different from the values specified by the manufacturers, contingent upon the load.
The decibel scale is a somewhat unusual because the human ear is extremely sensitive. Your ears can detect sound from something as slight as the brush of your fingertip against you skin to a very loud jet engine.
On the decibel scale, the smallest sound that can be heard is 0 dB. A sound that is ten times more forceful is 10 dB. A sound that is one hundred times more forceful than almost total silence is 20 dB. A sound that is one thousand times more forceful than almost total silence is 30 dB. Your own encounters inform you that distance influences the intensity of sound. The power is diminished significantly if you are far away. Each one of the ratings was obtained while standing close to the sound.
Any noise that is above eighty-five decibels can lead to a loss of hearing and that loss is caused by length of exposure to the sound and the power of the sound. Being exposed to eight hours of sound at ninety decibels can damage your ears. Any exposure to noises at are above one hundred forty decibels will cause immediate damage and physical pain.
Additional considerations include services and items. Does the generator come with a maintenance bundle or a warranty? Does it include a funnel, wheels, oil and a power cord? What will be the cost to have a professional conduct the installation?
You will have to set a budget because the price of a generator falls across a wide range. You have to make a determination about the amount you would like to spend.
Look at all the special features the quiet generators have to offer and determine the best special features that will meet your needs.

Many experts recommend introducing your business plan with definitions of the problem that your business solves and the solution your business offers.
That’s called “problem and solution,” and it’s quite common and quite useful—but it’s also too often an opportunity wasted.
Don’t just describe the problem and solution. Make people care.

I’ve been quite vocal with my concern that farming your business plan out is usually a bad idea.
A business plan is not a one-time task—it’s an ongoing practice. The writing, formatting, and cosmetics of a business plan are nowhere near as important as its contents (though they’re still important); and its contents should change often. Real companies with real business plans review and revise them often.
