What’s Mike’s Deal?
Ball Engineer II Red Label COSC Automatic
Ball builds some of the finest dress sport watches on the planet for the money, and by money we mean at full retail. Check this one out, incorporating tritium tube lume tech with an in-house caliber that is also a certified chronometer! This build features a polished 40mm x 13.5mm 316L stainless steel case and a brushed and polished contrasting solid link bracelet. The back is both screw down and sculpted and bezel is fixed, anchoring a beautifully finished AR coated sapphire crystal. Note the sculpted applied markers; each is mirrored and contains a tritium glass tube, which means your watch is not dependent on being charged by light to glow! Ball is among the first luxury builds to use tritium and is still known for the addition. Additional tritium tubes adorn the hour, minute, and sweep second hands. The dial is white with a precise deep vertical texture.
Now on to the star contained within; this watch is powered by the Swiss built BALL caliber RR1102-C self-winding automatic Certified COSC ( Controle Officiel Suisse des Chronometres ) Chronometer certified movement, which means you own among the most accurate mechanical automatic movements made (after all the Ball slogan is “accuracy under adverse conditions”)! Complications include the day and date displayed at 3 position. The crown is screw down and the bracelet features a dual deployant clasp. Shock resistance: 5,000Gs. Magnetic resistance: 4,800A/m. Water resistant to 5 ATM.
As we were getting into earlier, this watch is a solid buy at the 2699.00 retail, especially given that the in-house movement is a certified mechanical automatic chronometer. Reserve yours through TAW for just 1079, shipping included, NOT pre-owned, with full original presentation packaging and a solid one year warranty!
Because of the pricing we have on this, our source is now requiring that we put a time limit on it. If any remain when the countdown timer below hits all zeros, then they MUST come of the table. And, we don’t know if there will be any second chance on them in the future (all indications are pointing to no). We have already sold through about 20% of what is available to us. So, if you need to flip another watch or otherwise make arrangements to make this purchase, please do so quickly!
COSC Certified Chronometer
For those that may not know, the COSC (or Contrôle Officiel Suisse des Chronomètres) is a non-profit association which was created in 1973 by the Federation of the Swiss Watch Industry (aka FH) and the five major watchmaking districts of Switzerland. Namely Geneva, Vaud, Neuchâtel, Bern and Solothurn. Watch movements submitted are subject to fifteen days of testing in five positions and at three temperatures (8° C, 23° C and 38°C). The positions used are crown left, crown up, crown down, dial up, dial down and verification of additional all additional functionality of the watch movement. That is, date, chronograph, etc. The seven (7) criteria that must be met are average daily rate, mean variation in rates, greatest variation in rates, difference between rates in horizontal and vertical positions, largest difference in rates, thermal variation and rate-resumption. The tests that must be passed (for non-quartz movements) are as follows:
Minimal requirements in seconds per day (s/d), category 1 (diameter of the movement less than 20mm):
– average daily rate = -4 / +6
– mean variation in rates = 2
– greatest variation in rates = 5
– difference between rates in horizontal and vertical positions = -6 / +8
– largest difference in rates = 10
– thermal variation = ± 0.6
– rate-resumption = ± 5
Minimal requirements in seconds per day (s/d), category 2 (diameter of the movement equal to or larger than 20mm):
– average daily rate = -5 / +8
– mean variation in rates = 3.4
– greatest variation in rates = 7
– difference between rates in horizontal and vertical positions = -8 / +10
– largest difference in rates = 15
– thermal variation = ± 0.7
– rate-resumption = ± 6
Each uncased movement is individually tested for fifteen days, in five positions, at three different temperatures. The movements are fitted with a seconds hand and the automatic winding mechanisms are disengaged for the tests. Measurements are made daily with the aid of cameras. Based on these measurements, seven eliminatory criteria are calculated, each of which must be met (e.g., for movements of a diameter over 20 mm, the requirements, indicated in seconds/day, are noted in the table below). There is no ISO standard for quartz timepieces, but there is development in this field. ISO 10553:2003 specifies the procedure for evaluating the accuracy of quartz watches, individually and by lot, and the relationship between the accuracy tested and the accuracy classification given by the manufacturer.
If you are unfamiliar with the COSC certification process or you’d just like to really go down the rabbit hole and learn much more about it, we recommend that you watch the following video. This is a video put together by our friends at Long Island Watch as a part of their “Watch and Learn” series. As is the case with all of the videos from the folks at Long Island Watch, they have done an outstanding job at putting this together. It is very much recommended to all!
If you prefer an additional (and shorter) video, our friends at TheWatches.tv also have a very good video that covers the COSC process. It, too, is highly recommended.
