Catalogue description
Dealer description — Craft & Tailored
For 80 years before being totally consumed by the Japanese market and almost lost altogether to the infamous Quartz Crisis, Technos was a manufacturer run by a family of watchmakers, with a history that went all the way back to the year 1900. In 1970 the company was sold to General Watch Co. and thankfully the train just kept on going, because we got a stunning stock of funky dive and racing-style watches which we are still admiring 50 years later. Stock # TCHYTSG248 Brand Technos Style Sportsgraph Model 248 Serial H4XXXXXX Size Men's Material Stainless Steel Dial Silver Millimeters 38 Bracelet 2pc Handmade Leather Strap CASE & BRACELET The stainless steel case measures 38-millimeters and features a distinctive C-shaped design. Instead of the graceful curves usually employed on a case shape like this, Technos opted to cut the lugs in more drastically while also dropping them down deep under the case top. When combined with its still razor-sharp edges the design elicits something almost shark-like, streamlined with surprising movement. The watch is accompanied by a beautiful red-brown 2pc leather strap. DIAL & HANDS Featuring the famous regatta timer, this Sportsgraph shows a busy but impeccably designed dial. The silver base acts as the perfect backdrop to the bold red and blue of the regatta timer. The inner portion houses the timer, 60 seconds counter, and tritium-capped steel hour markers, while the outer dial features a light tachymeter scale. ACCESSORIES None. The watch is functioning and keeping time, previous service history is unknown.
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
Wristwatches
Bracelet watches were worn by women from the early nineteenth century — Breguet made one for Caroline Murat, Queen of Naples, in 1810–12 — but the wristwatch only became a man's instrument with military use and aviation in the early twentieth century. Between the World Wars it overtook the pocket watch; the 1920s and 1930s brought rectangular Art Deco cases, water-resistant cases and the first automatic winding systems.
After 1945 the wristwatch became a carrier of identity — dress watches, sports and dive watches, chronographs, calendars — produced by Swiss, American, Japanese, German, Soviet and Chinese industries. The quartz revolution after 1969 and the mechanical renaissance since the 1990s, including the rise of independent watchmakers, complete the story.
What to look for
- The reference number (between the lugs or inside the case back) and serial number, the starting point for dating.
- The calibre: its maker and number are often stamped under the dial or on the bridge.
- Originality of dial, hands and crown — refinished ('redial') dials are common.
- Case material marks: 18K/750, 14K/585, stainless steel, gold-filled, plated.
Dating clues
- Wire-lug cases: before c. 1925.
- Water-resistant screw-down cases: from 1926.
- Quartz movements: from 1969; sapphire crystals widespread after c. 1980.
