About this entry

79% of key specs known. Missing: 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). Brand specs for the SN033-G2 (written "SN0033-G2" in its spec list): NH35, 316L, 38.5mm, 48mm lug-to-lug (48.5mm on the SN033-G; the same case within San Martin's hand-measuring), 12mm (not stated whether including crystal), 20mm lugs, carved coin-pattern 316L bezel, top-hat sapphire crystal (recorded as a box shape) with AR coating (side not stated), sandblasted dial with applied indices in green, wine red, light brown or black, luminous hands, BGW-9 blue lume on hands and markers, screw-down onion crown, brushed screw-down caseback, 20mm quick-release leather strap with logo buckle, 100m, about 68g (read as on the strap). The listing also says "Green dial and red dial ones are changed to NH35 movement", which suggests the black and light brown dials may still have an earlier movement it doesn't name; the title and spec list name the NH35 for all, so NH35 is recorded. The steel bracelet ($263 for every dial) isn't described; its style and link count are from the photos. Leather is $218 for green and $231 for the others. Photos show no date window, so complications are time only. The green dial on leather was in stock on 2026-10-24; the other variations were out of stock.
