The SN075 with a Miyota 9120 multi-function automatic (day and month subdials, 24-hour indicator, date at 4:30), merging three listings that quote the same case: SN075-G-B ($418 on a two-tone rubber strap; the listing names a butterfly/push-button hidden clasp and its photos show a deployant on the strap), SN075-G-BR ($379 on a two-tone FKM rubber strap with 316L pin buckle; strap colours blue and red, light blue and white, green and white) and SN075-G-B2 with a waffle-pattern dial ($379 on rubber or $399 on the steel bracelet). Each comes in green, blue or light blue. Brand specs (all three): 316L, 43mm with a 38mm bezel, 46.5mm lug-to-lug, 11.9mm (not stated whether that includes the crystal), sapphire with AR coating (side not stated), curved lumed hands, BGW-9 blue lume on hands and markers, screw-down crown with 3D hexagon logo, screw-down 316L caseback, 100m. The brand quotes "lug to lug width 13mm" (the integrated strap and bracelet attachment, recorded as lug width); the B2's solid 316L bracelet is "24mm*18mm" with butterfly/push-button hidden clasp. Weight is about 173g on the B and B2 listings (not stated what was weighed) but about 118g on the BR, which is sold only on the FKM strap with pin buckle; 173g is recorded. The PT5000 and SW200 SN075-G (sn075-pt5000, sn075-sw200) is rated 200m and quoted at 11.4mm; the GMT is in sn075-hangzhou-6460. Inspired_by is read from the design (octagonal bezel with side "ears", horizontally striped dial); the brand does not name it. On 2026-10-25 the B listing had green and light blue in stock; the BR and B2 listings were out of stock.
