Catalogue description
Dealer description — Craft & Tailored
For a brand you've probably never heard of, Roamer has a long and fairly distinguished history in the world of watches. Founded in 1888 by Fritz Meyer in Solothurn, Switzerland, the brand initially specialized in making movements, with a specialization in cylinder escapements. In 1907, the brand unveiled a watch called the Soleure, which made Roamer more well-known for complete watches than just the movements inside. This Stingray from the '70s was part of the brand's foray into the increasingly popular world of diving, and it possesses all of the hallmarks of the quintessential dive watch – chunky case, highly legible dial, rotating bezel, oversized handset, etc. It's also a chronograph, which was less common in the dive world, and adds a bit of specialness to this piece. Plus, ticking away on the inside is the fantastic Valjoux 23, a highly respected movement. It's a fun piece with a historically significant movement, and one with a great backstory. SPECS Stock # RSTING023912900 Brand Roamer Style Stingray Chronograph Model 023-912.900 Serial N/A Size Men's Material Stainless Steel Dial Matte Black Millimeters 43 Bracelet Roamer "Gay Freres" Stainless Steel Bracelet CASE & BRACELET The chunky, asymmetrical tonneau-style case exhibits no obvious evidence of previously polished and shows honest signs of use. The original bi-directional bezel remains deep black in coloration with almost no signs of age. The watch retains its original Roamer-signed screw-down crown and unsigned pump pushers at 2 and 4 o'clock. The case back shows appropriate signs of use for its age while all the factory markings are still legible and intact. The watch is supplied on its original Roamer-signed Gay Freres stainless steel bracelet, which retains 20 links that show minimal stretch and will fit up to an 8 1/2-inch wrist. DIAL & HANDS The original matte black dial is in virtually flawless condition, with no visible signs of wear or age. The tritium lume plots have aged to a nice pumpkin coloration and show no degradation under UV light inspection. The oversized white baton-style hands have inlaid lume that has aged to a slightly lighter color than the dial, under UV light inspection the lume in the minute hand features a subtle crack at the tip and remains stable. The chronograph hand is a nice bright red that pops off the dial, and complements the red in the inner and outer bezels nicely. ACCESSORIES
Historical context
Quartz Revolution (1969 – 1990)
Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.
Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

Atlas type guide
Chronographs and split-seconds watches
A chronograph is a watch with an additional seconds hand that can be started, stopped and returned to zero independently of the timekeeping. Louis Moinet built an early example in 1816 and Nicolas Rieussec a recording 'chronographe' in 1821; Adolphe Nicole's heart-shaped reset cam (patented 1862) made the modern return-to-zero possible. Split-seconds (rattrapante) chronographs add a second hand that can be stopped for intermediate times; flyback chronographs restart instantly.
Chronographs were essential tools for doctors (pulsometer scales), artillery (telemeter), engineers and sport. In wristwatches, Valjoux, Venus, Lemania and later the automatic chronographs of 1969 (Zenith El Primero, the Chronomatic Calibre 11 group and Seiko 6139) are milestones.
What to look for
- Push-pieces on the case band or a single button in the crown (monopusher).
- Subsidiary registers for minutes and hours; tachymeter, telemeter or pulsometer scales.
- Column wheel versus cam control visible in the movement.
- Calibre markings of specialist makers (Valjoux, Lemania, Venus, Landeron).
Dating clues
- Pocket chronographs with heart cam reset: after 1862.
- Wrist chronographs: from c. 1910; two-button designs from the 1930s.
- Automatic chronographs: from 1969.
