Here we have a 2023 Squale 50 ATMOS Militaire Blasted 1521 Automatic with a 41.5mm bead blasted 316L stainless steel case; the 1521 pays tribute to their dive heritage, specifically to their classic 1970s Charles von Büren-designed Squale 1521; they became the official suppliers to the Italian Navy and paratroopers. Bevel edges lead to a lug-to-lug length of 48.5mm and a case thickness of 12.5mm, ensuring a comfortable fit on your wrist; at 4 o’clock, a signed screw-down crown was slightly recessed into the case. A unidirectional bezel has a black aluminium dive insert with large lume-coated numerals holding a flat sapphire crystal AR coated above a matte black dial, and an outer minute track has baton indexes coated in Superluminova C3 luminescence marking the hours. The hands consist of a slim orange minute hand and a broad sword hand filled with the same luminance complemented by a counterweighted second hand. At 12 o’clock, underneath the inverted triangle, we have the Squale motif and "Militaire" at 6 o’clock “Automatic 500m”, completing this military-inspired dive watch. On the reverse, a screw-down case back with the Squale “Professional” acid-etched in the centre, inside an automatic Sellita SW 200-1, 26 jewels, 28,800 beats per hour; the movement has hacking and hand winding for your convenience. The watch comes fitted on its 20mm Squale tropic rubber strap with a signed buckle. It comes with its Squale presentation box, swing tag, travel pouch, spring bar removal tool, and papers.
