About this entry

53% of key specs known. Missing: lug-to-lug, weight, hardening, crystal, AR coating, crown, lume.

The bronze GMT build of Undone's 40mm Basecamp, on the Time Module (Seiko) NH34A; the steel Basecamp GMT, the titanium Basecamp Titanium GMT and the NH35 Basecamp Bronze are separate models. Spec table: "Japanese GMT NH34 Automatic Winding Mechanism", bronze case, "LEXAN Polycarbonate" lens, 40mm excluding the crown, 15mm including the crystal, and "3 ATM / 30 METERS". The water resistance is recorded as 100m because the description ("10 ATM"), the dial ("100m = 330ft") and the caseback photo ("pressure tested to 100 meters") all say so. The description's "40mm stainless steel case" contradicts the spec table, the bronze photos and the caseback ("CuSn8 bronze case", "316L stainless steel back"), so bronze is recorded. The crystal is a plastic (polycarbonate) one; the schema has no polycarbonate category, so the material is left blank (the page summary calls it domed). The dial has no date window although the NH34 has a date. The 20mm lug width is from the strap photo's file name, not a stated spec; a UV photo shows lumed indices and hands, compound not stated. Whether the 24-hour bezel rotates is not stated. No lug-to-lug, weight or crown details are published. Editions. Quest (listed 2024-01, BCP-BRN-QST, USD 460): blue dial and 24-hour bezel, bronze-tone indices and hands, red-tipped GMT hand, brown strap; sold out on 2026-10-30 and still listed.
