Sea-Gull ST19 Moon Phase Chronograph – Bronze-Tone Case / Brown Alligator-Grain Leather

Condition: Pre-Owned. This is a pre-owned timepiece, professionally inspected, timed and tested by Watch Tailors — presented in excellent working order, with the chronograph, moon phase and date all functioning as they should.

A genuine mechanical chronograph with real complications at a price that normally buys a quartz dress watch. The Sea-Gull ST19 Moon Phase Chronograph pairs China's most storied chronograph movement with a warm bronze-tone case, a cream guilloché dial and a brown alligator-grain leather strap on a signed Sea-Gull deployant clasp. Part of our Curated & Tested by Watch Tailors selection — every piece is inspected, timed and checked in-house before it ships.

The ST19 Column-Wheel Chronograph

Hand-wound, no battery, no rotor. The ST19 is a true column-wheel chronograph built on tooling Sea-Gull acquired from the legendary Swiss Venus 175 — the same architecture that powered the 1963 Chinese Air Force pilot's watch. Column-wheel actuation is what gives the pushers their crisp, mechanical click, and it is a construction almost never found at this price. Wind it each morning and watch it run.

Working Moon Phase

A deep blue lacquered moon-phase aperture sits at six o'clock, with a gilt moon and gold stars tracking the lunar cycle across the dial. It is a live, working complication — not a printed decoration — and it turns a chronograph into something you actually look at when you are not timing anything.

Pointer Date & Chronograph Registers

The dial is a genuine four-register layout: a pointer date on the 1–31 scale at twelve o'clock, running small seconds at nine, a 30-minute chronograph counter at three, and the moon phase at six. A long central sweep hand times the chronograph seconds against the outer minute track.

Bronze-Tone Case & Exhibition Caseback

A warm bronze-tone case with sculpted teardrop lugs, a fluted onion crown and two cylindrical chronograph pushers — classic mid-century chronograph proportions. The domed crystal gives the dial its vintage curvature. Flip it over and a stainless steel exhibition caseback puts the entire hand-wound movement on display: bridges, gear train, jewels and the chronograph levers all visible and in motion.

Cream Guilloché Dial

Cream dial with fine engine-turned guilloché texture, applied rose gold-tone Roman numerals and a railroad minute track. The three subdials are individually textured, catching the light at different angles as you turn the watch.

Brown Alligator-Grain Leather Strap

Genuine leather in a brown alligator grain with tonal stitching, closing on a signed Sea-Gull stainless steel butterfly deployant clasp — no loose tail, no wear on the strap tip.
