The TBR from Arnold & Son is a beautiful timepiece that combines highest precision with aesthetic perfection. It is part of the Instrument Collection.
Its pure, timeless design takes its inspiration from the later instrument-style chronometers produced by Roger Arnold. These were reliable and rugged enough to withstand the hardships of life on the high seas combined with the down-to-the-seconds precision needed by marine navigators to determine longitude.
The Arnold & Son TBR is a masterpiece of reduced simplicity. The initials stand for the watches two complications – true beat and retrograde. While the time is displayed in an off-centre subdial at 9 o’clock, the two complications occupy the middle of the dial and command the front of the stage.
Dominating the face of the watch is the central true beat (or independent) seconds. The true beat seconds is a rarely found complication, and its combination with an automatic winding system needs a good amount of technical expertise. It was made possible by a system comprising a sophisticated double wheel, an oscillating pinion and a pallet mechanism. This solution is highly complex and calls for state of the art fabrication technology.
The “R” of TBR – retrograde – is a description of the watches second complication, the date display. The second most conspicuous element on the dial, the date display shows the dates 1 to 31 in Arabic numerals with intermediate dots for the even dates. a slim, undulating hand advances a day at a time until it reaches the end of the month. At midnight that day the hand springs back (hence retrograde) to 1 and the process begins all over again.
This watch is powered by the A&S6008, an exclusive in-house mechanical self-winding movement. It works with 28,800 vibrations per hour and provides a power reserve of 50 hours. The calibre is hand-finished.
The TBR from Arnold & Son is available in either a rose gold case or in stainless steel, measuring 44 millimeters in diameter. The case is water-resistant to 30 meters and comes with a hand-stitched brown or black alligator leather strap.
