About this entry
68% of key specs known. Missing: lug width, weight, hardening, end links, link attachment, clasp micro-adjust.
The SN033 is a pilot-style case with a carved coin-edge steel bezel and an onion crown, sold as the 38.5mm SN033-G (YN55A, sn033-38-5mm-yn55a), the 38.5mm SN033-G2 (NH35, sn033-nh35) and the 39.5mm SN033-C (YN55A, sn033-39-5mm-yn55a). The SN033-C quotes a 39.5mm diameter against 38.5mm for the SN033-G and G2, a difference beyond hand-measuring noise, so it is kept as its own model. Brand specs for the SN033-C (written "SN0033-C" in its spec list): YN55 (recorded as the Epson YN55A, as on the other San Martin YN55 models), 316L, 39.5mm, 48.5mm lug-to-lug, 11.95mm including crystal, carved coin-pattern 316L bezel, sapphire with AR coating (side not stated), green, salmon, silver or purple dial with applied indices, lumed bar hands, "BGW-X1" blue lume on hands and markers, screw-down onion crown, brushed screw-down caseback, quick-release leather strap with logo buckle, 100m. Lug width and weight are not stated. The photos show Chinese-numeral hour markers; the boxed 四 at 4 o'clock is a marker, not a date window, so complications are time only. The steel bracelet ($258; $218 on leather) isn't described; the photos show a five-link jubilee-style bracelet. Several variations (salmon and silver on leather, green and salmon on the bracelet) were in stock on 2026-10-24.
