TBR Watch by Arnold & Son at BaselWorld 2012

At the annual exhibition of BaselWorld 2012 the company Arnold & Son has introduced a watch TBR (True Beat Retrograde). As the name implies, the novelty has a function True Beat, better known under the term "dead seconds" or "stop-second."
The tradition of using the function "dead seconds," goes back to the XVIII-XIX centuries: the scheme of the complication appeared in the XVIII century, but had a wide application in the XIX century. Complications are mainly used in marine chronometers, which allowed more accurately determination of the longitude.
One of the first, who noticed a complication and later used in high-precision marine chronometers was Sir John Arnold (the founder of Arnold & Son).
In the watch with the function of stop-second the second hand moves with a jump of times per second (in the traditional schemes, it moves in small steps - 5-10 times per second).

The second part of the name indicates a retrograde date. Retrograde indicators are moving not in a familiar circle but in an arc, and, having reached its end, are reset to the initial position by a special spring.
The functions of the True Beat and Retrograde are complicated the manufacturing mechanism A& S6008 (automatic winding, diameter - 30.4 mm, thickness - 7.79 mm, 34 jewels, the vibration frequency of the balance - 28 800 pc / h, power reserve - 45 hours). The caliber has also a function of indicating hours and minutes. The mechanism is set in a round case with a diameter of 44 mm.
The TBR watch is presented in two versions – in a stainless steel case (Ref. 1ARAS.S01A.C121S) and 18 K rose gold (Ref. 1ARAP.W01A.C120P).
