About this entry

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

The bronze-cased build of Undone's 40mm Basecamp on the Time Module (Seiko) NH35A; the steel Basecamp and the NH34 GMT builds are separate models. Spec table on both listings: "Japanese TMI NH35A/ NH39 Automatic Winding Mechanism", CuSn8 bronze case, "LEXAN Polycarbonate" lens, 40mm excluding the crown, 15mm including the crystal, 10 ATM / 100m. Neither dial shows the NH39's open-heart aperture or 24-hour indicator, the caseback photos show an NH35A and the Classic Bronze Date page summary names the NH35A "with date", so the NH35 is recorded; the Cali Bronze dial has no date window. The crystal is a plastic (polycarbonate) one; the schema has no polycarbonate category, so the material is left blank (the page summaries call it domed). The caseback photos read "CuSn8 bronze case", "316L stainless steel back" and "pressure tested to 100 meters" around a see-through back. The 20mm lug width is from the strap photo's file name ("20mm_nato"), not a stated spec. No lug-to-lug, weight or lume details are published, and crown details only for the Destro Popeye (below). The Cali Bronze listing is customizable; the store data shows extra configurator price points (USD 405 to 520) without saying which options they cover, and the USD 400 base price is recorded. Editions. Cali Bronze (BCB-CAL-BLK, USD 400): black California dial, bronze bezel, black nylon strap. Classic Bronze Date (listed 2025-09, BCB-CLS-BLD, USD 400): blue dial with orange hour hand and date, navy nylon strap; sold out on 2026-10-30 and still listed. POPEYE & FRIENDS "Destro" Popeye (COL-POP-PPE, USD 480, 250 pieces serialised on the caseback; sold out on 2026-10-30): a left-hand crown build (the crown at 9 o'clock), because Popeye holds his spinach can in his left hand; navy dial with Popeye and snowflake markers, navy bezel with numerals at 15, 30 and 45, navy Cordura strap (photo filed "20mm_Crodura"); its spec table matches this model's ("NH35A/ NH39", CuSn8 bronze, LEXAN polycarbonate, 40mm, 15mm including the crystal, 100m), its side photo is the bronze Basecamp case ("basec_sidepix_case_bronze"), and the dial shows no NH39 aperture.
