Submariner-style diver; the store calls the quartz H3 siblings "Sub". The listing offers the same watch with a Seiko NH35 or a Miyota 8215 automatic (both quoted at 41h); this file is the Miyota 8215 version. The same watch with a Seiko NH35 is $139 (see h3ac). The 8215 variants use SKU prefix AD2503 on the store, so this build is named by that code, as other Miyota 8215 builds are (AD2505, AD2525, AD2533); it was first published as "H3AC (Miyota 8215)" (file h3ac-8215). Brand specs: 316L case and caseback, 41mm excluding crown, 48mm lug-to-lug, 13mm, 20mm lugs, 120-click unidirectional ceramic bezel, sapphire with anti-reflective coating (side not stated), Swiss BGW9 + C3 Super-LumiNova (blue-green glow), screw-down crown and caseback, 200m. Bracelet is not described in the listing; the product photos show a three-link Oyster-style steel bracelet, so style and links per row are from the photos. Weight, end links, link attachment and clasp are not stated. A second listing, "Two Color Sub NH35/8215 Mechanical Watch H3AC" (same spec text: "Model: H3AC", "Japan NH35/8215 automatic, 41 hours", 120-click ceramic bezel, 41mm, 48mm, 13mm, 20mm, 200m), sells the same black-dial watch with two-tone ceramic bezels: black/green and blue/red with a 24-hour (GMT-style) scale, although the watch has no GMT hand, and black/blue with the 60-minute dive scale. The model's 60-minute bezel scale therefore doesn't apply to the black/green and blue/red two-tone variants; bezel colours and scales are from the photos. Its Miyota 8215 options also carry AD2503 SKUs (AD2503-3 black/green, AD2503-4 black/blue, AD2503-14-2 blue/red): $129 for black/green and black/blue, but $139 for blue/red, the same as the NH35 options, recorded as listed (no crossed-out prices; all in stock on 2026-10-21). The same listing's NH35 options are in h3ac.
