Arnold & Son has long treated chronometry as more than a historical talking point.
With the new DSTB Stop-Seconds, the brand gives one of its most distinctive displays a practical upgrade, allowing the exposed true seconds hand to be halted and set precisely to the second.
The result is a technical watch with a clear connection to marine timekeeping, but also one with plenty of theatre on the dial.
At a glance
- Arnold & Son has introduced the DSTB Stop-Seconds in two limited-edition precious-metal versions.
- The watch combines a dial-side true seconds mechanism with a crown-activated stop-seconds function for precise synchronisation.
- Each version is limited to 18 pieces, priced at CHF 46,000 in red gold and CHF 56,800 in platinum, including VAT.
A true seconds display with maritime roots
The DSTB sits inside Arnold & Son’s chronometry family, one of three collection pillars that also include astronomy and world time.
Its name stands for Dial Side True Beat, and the defining feature is exactly that: a true seconds, or deadbeat seconds, mechanism placed prominently on the dial rather than hidden beneath it.
The complication links naturally to the legacy of John Arnold, the 18th-century English chronometer maker whose precision instruments were supplied to the Royal Navy.
Those marine chronometers relied on highly legible seconds readings at a time when accurate navigation could decide the course of a voyage.
In longitude calculation, a deviation of one second from GMT could translate to a positional error of 463.8 metres, which explains why the seconds indication carried such practical importance at sea.
The true seconds display also has a distinct visual character.
Rather than sweeping continuously, the long blued seconds hand advances in clean one-second jumps, giving the watch the deliberate cadence of a precision instrument.
The stop-seconds upgrade
Marine chronometers were built to keep running uninterrupted through a voyage, while navigators used separately synchronised pocket watches to carry reference time on deck.
The DSTB Stop-Seconds draws from that culture of exact synchronisation by adding a crown-activated function that halts the seconds hand for setting.
It’s a small but meaningful addition, because a true seconds display feels incomplete if the watch can’t be aligned cleanly with a reference signal.
Arnold & Son first introduced the dial-side true seconds architecture in the DSTB in 2014, then returned to the idea in 2023 with a more wearable 42mm case and a more compact version of the A&S calibre 6003.
This new edition keeps the 42mm format and adds the stop-seconds function through the in-house A&S6303 automatic movement.
The movement runs at 4Hz and provides a 55-hour power reserve.
Two precious-metal editions with grained dials
The DSTB Stop-Seconds arrives in two executions, each limited to 18 pieces.
The red gold version is paired with a Cliff Grey PVD-treated grained dial, a colour chosen to evoke the cliffs of John Arnold’s native Cornwall.
The platinum model uses a Kingsand PVD dial, a golden tone inspired by the brass plates of Arnold’s movements.
Both watches use a contemporary grained surface, with hours and minutes shown on a concave opal sub-dial at 4 o’clock.
The rest of the dial is dominated by the exposed deadbeat seconds works, arranged beneath three openworked bridges.
Those gold bridges are shaped like wishbones, mirror-polished and built in three dimensions, giving the mechanism both height and structure.
Below them, the gears and blued anchor-shaped lever remain visible, adding a direct maritime reference without leaning on obvious decoration.
A domed sapphire crystal covers the dial, while a flat sapphire crystal on the caseback opens the view onto the movement.
Finishing is extensive, with radiating Côtes de Genève on the bridges, circular graining on the mainplate, blued screws and hand-chamfered edges.
The openworked 22k gold rotor is engraved with guilloché and Arnold & Son’s anchor emblem.

A chronometer idea made visible
The appeal of the DSTB Stop-Seconds is that it doesn’t reduce precision watchmaking to a hidden technical claim.
It puts the regulating idea on display, then adds the one function that makes the jumping seconds hand more useful when setting the watch.
For collectors drawn to Arnold & Son’s chronometry story, this is a compact and more complete expression of one of the brand’s signature complications.
