LAST ONES IN THIS SIZE AND STYLE! We've sold 13 of these to satisfied customers here, but now our supply is about to run out. Vintage Swiss vintage divers watch band with the big holes and 20mm ends, plus the famous Tropic buckle signed ACIER on back. The ideal original period vintage Swiss dive band for your Rolex Submariner GMT-Master Sea-Dweller 20mm lug watch. NO WATCH IS INCLUDED IN THIS AUCTION; WATCHES SHOW FOR EXAMPLE ONLY. You are buying one watch strap. A super rare size and style 1960s/70s Tropic band to find. This is a vintage NOS genuine Tropic dive strap made in Switzerland -- an authentic original Swiss Tropic Sport signed band. The exact same band a Rolex Authorized Distributor would have put on your vintage Rolex Submariner as an original accessory all the way back to the 1960s and '70s, if the customer wanted a dive band on it. These are long out of production and nearly impossible to find in 20mm. The Swiss Made ones are thicker and more supple than the unsigned type. This 20mm straight Tropic could work well on the watches as shown in this ad - NO WATCH INCLUDED IN AUCTION. Also compatible period-correct band for a Rolex Sea Dweller or Rolex GMT-Master sports watch. This band is sized to fit many wrists. Measures 7 ½ inches long, with the pieces placed end to end (115mm/75mm), not counting the buckle. At the longest, with the strap pieces together and the tang in the last hole, the strap is 6 5/8 inches long and you can size it all the way down to just 5 ¼ inches long closed. Band is 4.5mm thick where it meets the watch and 2.4mm thick at the tail end. Nice pliable, soft rubber. Single sliding strap keeper. This 20mm Tropic band comes with the most desirable Tropic Premium buckle signed Acier on back. Strap buckle end is 16mm if you want to substitute a vintage Rolex buckle of your own. I also have the 20mm Swiss perforated small holes style bands with the waffle finish.
