Short description: Arnold & Son has introduced the DSTB Stop-Seconds, a limited-edition evolution of its distinctive deadbeat-seconds wristwatch. Combining an exposed mechanical complication with a newly integrated stop-seconds function, two precious-metal versions bring technical refinement and traditional chronometry into the spotlight of independent Swiss watchmaking.
◉ 36 watches will be produced: 18 in 5N red gold and 18 in 950 platinum.
◉ The new stop-seconds function allows the prominent jumping seconds hand to be halted when synchronising the watch.
◉ The in-house automatic A&S6303 movement delivers 55 hours of power reserve, combining traditional mechanics with an unusually theatrical dial architecture.
A Mechanical Display
Arnold & Son’s DSTB collection has always been built around one distinctive feature: the deadbeat-seconds complication.
Unlike conventional mechanical watches, where the seconds hand moves continuously, a deadbeat-seconds mechanism advances once every second. The result resembles the movement of a traditional quartz watch, but is achieved entirely through mechanical engineering.
The DSTB, short for Dial-Side True Beat, makes this mechanism part of the visual experience. Gears, bridges and the release mechanism are exposed directly on the dial, allowing the wearer to observe how mechanical energy is converted into precise one-second movements.
The new DSTB Stop-Seconds introduces an additional function that makes this complication more practical.
The Stop-Seconds Innovation
The defining upgrade is the ability to stop the seconds hand through the crown when setting the time.
This is particularly relevant for a watch whose identity revolves around the precision and visibility of its seconds display. The mechanism must not only produce individual one-second jumps but also stop and restart reliably without compromising its operation.
The watch is powered by Arnold & Son’s automatic A&S6303 calibre, featuring a 55-hour power reserve and 4Hz frequency.
Its finishing includes radial Côtes de Genève decoration, blued screws, hand-finished bevels and an openworked 22-carat gold rotor.
The technical architecture is complemented by a concave white-opal hours-and-minutes subdial, adding another layer of depth to the dial.
Two Precious-Metal Editions
The DSTB Stop-Seconds arrives in two configurations, each limited to just 18 examples worldwide.
- Cliff Grey: 18-carat 5N red-gold case with a textured grey dial.
- Kingsand: 950 platinum case with a warm, pale-gold dial treatment.
Both watches measure 42mm in diameter and 12.95mm in thickness. Water resistance is 30 metres.
The Swiss retail prices are CHF 46,000 for the red-gold edition and CHF 56,800 for the platinum version, including VAT.
The extremely limited production positions the watches firmly within the specialist haute horlogerie segment rather than the broader luxury-watch market.
Collector Appeal and Market Positioning
The DSTB Stop-Seconds occupies a specialised segment of the luxury-watch industry where mechanical innovation, traditional finishing and production exclusivity are central to its appeal.
The addition of a stop-seconds function may appear relatively small compared with a tourbillon or perpetual calendar. However, on a watch designed around the deadbeat-seconds display, it represents a meaningful functional improvement.
For collectors, the combination of exposed mechanics, precious-metal construction and a production run of only 36 pieces creates a distinctive proposition.
The launch also reinforces the position of independent high-end watchmaking within the luxury market, where technical differentiation remains an important element of brand identity.
