Arnold & Son adds a stop-seconds function to its DSTB true-beat complication. Two editions of 18 pieces each, in red gold and platinum. Middle East collectors, take note.
The Facts First
- Adds a stop-seconds function to the existing DSTB true-seconds complication — a combination Arnold & Son has not offered before in this collection.
- Two limited editions of 18 pieces each: 18-carat 5N red gold with a Cliff Grey PVD dial, and 950 platinum with a Kingsand PVD dial; both measure 42 mm.
- Powered by the in-house automatic A&S6303 calibre, 28,800 vph, with a 55-hour power reserve and a Swiss lever escapement.
- Case backs reveal a 22-carat gold oscillating weight decorated with guilloché and John Arnold’s anchor ex-libris; water resistance is rated to 3 bar.
The Innovation
Stopping a true-seconds complication is considerably more complex than stopping a conventional seconds hand. The deadbeat mechanism stores and releases energy every second under constant tension; a dedicated stop lever had to be engineered to arrest it cleanly and restart it the moment the crown is pushed back in. Arnold & Son states the mechanism is visible neither from the dial side nor through the case back, yet its engineering took significant development time to resolve.
The practical result: pull the crown, the seconds hand freezes. Push it back in, the hand restarts instantly. For a watch whose defining purpose is legible, dead-accurate seconds, the addition is logical rather than decorative.
The Execution
On the dial, gold bridges and a release mechanism ending in a fire-blued steel marine anchor frame the true-seconds display. The long seconds hand jumps sharply from marker to marker — no sweep, no drift. Roman-numeral sub-dials are cut from white opal, set within red gold or platinum rings, their concave surface referencing the raised enamel dials John Arnold produced for the Royal Navy.
At the bench, finishing follows Arnold & Son’s standard for the line: bridges carry radial Côtes de Genève, hand-chamfered edges, blued and profiled screws, and a circular-grained main plate. The manufacture in La Chaux-de-Fonds develops, machines, assembles and regulates every component in-house.
The Broader Significance
The historical grounding is direct: John Arnold supplied precision detent-escapement timepieces to the Royal Navy, where his balance wheels beat at 7,200 vibrations per hour — once every half-second. A positional error of one second against Greenwich Mean Time translated to 463.8 metres at sea. The stop-seconds mechanism on this watch answers the same demand for synchronisation, transferred from an eighteenth-century quarterdeck to a contemporary wrist.
At 18 pieces per material, the DSTB Stop-Seconds sits at the tightest end of Arnold & Son’s production. For collectors across the Gulf who track the brand’s chronometry line, both references represent the most technically complete version of the DSTB to date.

Frequently Asked Questions
What movement powers the Arnold & Son DSTB Stop-Seconds?
The watch is driven by the in-house automatic A&S6303 calibre, beating at 28,800 vibrations per hour and offering a 55-hour power reserve. The self-starting movement is what makes the stop-seconds function practically viable.
How does the stop-seconds function work on the DSTB Stop-Seconds?
Pulling out the winding crown halts the seconds hand instantly, allowing the time to be synchronised to the exact second against a reference source. Pushing the crown back in restarts the deadbeat mechanism immediately.
How many pieces of each DSTB Stop-Seconds edition are produced?
Each version is limited to 18 pieces: 18 in 18-carat 5N red gold and 18 in 950 platinum, totalling 36 watches across both references.
What is the difference between the Cliff Grey and Kingsand dial versions?
The red gold model carries a Cliff Grey PVD dial, a shade inspired by the cliffs of John Arnold's native Cornwall, paired with a matching alligator strap. The platinum model has a Kingsand PVD finish, referencing the gilded brass plates of Arnold's original movements, and is paired with an ink-blue alligator strap.
Is the Arnold & Son DSTB Stop-Seconds available in the Middle East?
The brand has not named a specific retail channel in the press release. Collectors in the region should contact Arnold & Son or an authorised retailer directly to enquire about availability.
