For sale is a MINT condition Squale 1521 ("50 Atmos") COSC certified. Upgrades to the COSC edition include applied indices and lightly engraved + lumed numerals on the bezel. I've always felt that the standard 1521 was a bit flat-- this COSC version improves on the legend with a much more premium, 3D aesthetic. This black 1521 is very dynamic and often takes on a beautiful mocha tint in sunlight. It's been worn just once at home-- the included original Italian leather strap has never been unpackaged. The assembly date listed on the Chronometer certification is 04/05/2023. The tropic rubber strap has slight curvature due to being worn once. **Measurements:** Diameter: 42mm Thickness: 12.5mm Lug to Lug: 48m Lug Width: 20mm It wears smaller, more like a 39-40mm, similar to a BB58. The lugs curve downward to hug the wrist and the mid-case design makes it wear slim.
