Vintage Swiss RACING  dive band with the big holes and 20mm ends. The ideal original Swiss dive band for your Rolex Submariner GMT-Master Sea-Dweller or other 20mm lug watch.

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 an Omega Speedmaster 321 with 20mm lugs or a Rolex Submariner. Also great for a Rolex Sea Dweller or Rolex GMT-Master /Datejust 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 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 BLUE 20mm Tropic band comes with the most desirable premium Tropic buckle signed Acier on back. Strap buckle end is 16mm if you want to substitute a vintage Rolex buckle vintage Heuer buckle Longines Omega or Breitling watch buckle of your own.
