About this entry
80% of key specs known. Missing: weight, hardening, AR coating.
Brand specs: "Time Module NH35A", 316L, 43mm excluding crown, 49mm including lugs, 13.5mm including crystal, 20mm lugs, sapphire (no AR coating mentioned), dark blue or black dial with a vintage finish, wide sword hands, C3 lume in a vintage tone glowing yellow-green, screw-in crown and caseback with a pressed shark logo, rubber strap with a solid "fine-tuning stretch" dive clasp, 200m; weight not stated. Photos show a 60-minute dive bezel (direction and insert not stated) and a date window at 6 rather than the NH35's usual 3; the spec text names the NH35A, so it is recorded. The clasp is described only as above, so no micro-adjust type is recorded. The dark blue dial without logo is $199; with the logo, and the black dial either way, $205. Rubber straps in blue, black and orange appear in photos but are not offered as options. No bracelet is offered. Every variation showed "Out of stock" on 2026-10-25, so production status is unknown.
