Catalogue description
Dealer description — Watches of Knightsbridge
The Universal Genève Tri-Compax ref. 88101/02, known among collectors as the “Evil Clapton,” is the stealthier, black-dial sibling to the famed Clapton Tri-Compax. Its black dial with contrasting white registers, and clean triple-calendar chronograph layout give it a bold, modern edge while retaining the charm of 1960s UG design. Powered by the celebrated caliber 281 and housed in a refined 36mm stainless-steel case, the 88101/02 pairs technical pedigree with standout aesthetics. Rare, stylish, and unmistakably iconic, the “Evil Clapton” remains one of UG’s most coveted vintage chronographs.

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.
