The HU-02 from Singapore maker Horologically Unique has no hour hand and no minute hand. A single Art Deco arrow turns around the dial with a window at its tip that shows the hour, and the arrow’s position against the minute track tells the minutes.
The display revives Robert Cart’s Chronoscope, built for pocket watches in the 1920s, and the brass version starts at $3,850.
How the arrow tells the time
Horologically Unique calls the display a wandering and jumping hour with a rotating minutes indicator, and the name describes exactly what happens on the dial. The arrow sweeps the full circle once an hour, and as it crosses from 59 to 60 the window at its tip jumps to the next hour.
The arrow itself carries an Art Deco guilloche, cut into both the cream Classic dial and the two-tone silver grain dial of the Silver Speciale.
One glance is enough.

Naval brass case, mirror polished with a protective coating · Cream dial · Sand Calf strap

The case is a 38mm disc with a domed crystal
The case measures 38.0mm across and 38.0mm lug to lug, so there’s no overhang past the strap line at either end, and the whole watch sits on the wrist as a simple round disc. Thickness runs 11.5mm with the domed sapphire crystal fitted and 10.1mm without the glass counted, and the crystal carries anti-reflective and anti-fingerprint coatings.
The strap attaches on an 18mm curved lug width and tapers from 18mm to 16mm at the buckle, with quick-release fittings on both versions.
It wears smaller than it measures.
Underneath sits a modified ETA 2824-2
The base movement is an ETA 2824-2 automatic, modified with a custom wandering hour module that Horologically Unique fits to drive the rotating arrow and the jumping window. The finishing is perlage and Cotes de Geneve, visible through the caseback, and the power reserve runs 32 hours. Water resistance is 3 ATM, which is splash territory rather than swimming depth.
Park it Friday and it’s stopped by Sunday.
Two versions and a short window to claim one
The Classic pairs a mirror-polished naval brass case, protected by a coating, with a cream dial and a Sand Calf strap at $3,850. The Silver Speciale runs a mirror-polished 316L steel case with the silver grain dial and a Taupe Calf strap at $3,980. Both prices include shipping, though customs and taxes sit with the buyer, and the maker’s FAQ warns that US buyers may face significant tariffs on top.
Allocations stay open until the end of December 1, 2026, delivery is estimated for June to July 2027, and the maker states the run is limited by production and won’t be made again after this window. The trade is plain: you pay now and wait about seven months for a watch from a one-person project, and in exchange you get a display almost nobody else sells at this price, in a run that won’t repeat.
The wait is the real price.

Buy the Classic at $3,850 if a brass case and the cream dial fit the collection you’re building, and take the Silver Speciale at $3,980 if you’d rather have the steel version. Skip both if you need a watch on your wrist this year, because nothing about this order arrives before next summer.
