Undone's 40mm automatic pilot watch, a "tribute to the first-ever rotating bezel" invented by P.V.H. Weems, launched in 2020 (aBlogtoWatch's hands-on of the Commando, September 2020, USD 365). Undone sells it in its Basecamp collection (the listings are tagged "basecamp" and its 20mm Metal Band is sold "for Basecamp & Aero watches"), but it is recorded apart from the Basecamp because its case adds a bezel lock: aBlogtoWatch describes a 60-second bezel that turns freely in both directions and is clamped by a "crown-like screw at 2 o'clock", which the Worldtimer listings call the "Weems bezel lock" (red anodised aluminium on the Worldtimers); the winding crown is at 4 o'clock in the photos. Spec table, identical on all three listings: "Japanese TMI NH35A/ NH39 Automatic Winding Mechanism", 316L steel case, "LEXAN Polycarbonate" lens, 40mm excluding the crown, 15mm including the crystal, 10 ATM / 100m, the same figures as the Basecamp's. No dial shows the NH39's open-heart aperture or 24-hour indicator, aBlogtoWatch names the NH35A, and the Worldtimer dials show the date through a ring of numerals, so the NH35 is recorded; the Commando dial has no date window. The crystal is a domed plastic (polycarbonate) one, which the schema has no category for, so the material is left blank. The caseback photos show a see-through back. The 20mm lug width is from Undone's metal band listing ("Compatible with Basecamp and Aero watches (20mm lug width)"); the Lindbergh's bracelet is that band in black (same photo), whose SKUs read "3link", hence three links per row. No lug-to-lug, weight, lume type or crown construction is published. Both Worldtimer listings were created in June 2023. Editions. Commando (ARO-CMD-SLB, USD 365): polished steel case and brushed 60-second bezel, sandblasted black dial with cream Arabic numerals, a 13-24 inner ring and a red seconds hand, black Cordura strap; sold out on 2026-10-30. Worldtimer Doolittle (ARO-WTR-DOT, USD 399): black-coated case, green dial with the date on a numeral ring, world-time bezel with 12 cities ("Keep track of time on 12 timezones at a glance"), red lock crown, green Cordura strap; sold out on 2026-10-30. Worldtimer Lindbergh (ARO-WTR-LBH, USD 499): the same in black with a black dial, on the black steel bracelet. Chinese Hour Snake (2025, BCP-AER-CHH-SHB, USD 375; "limited edition, with only 88 pieces"): for the Year of the Wood Snake; black-coated case, black dial with the twelve Chinese double-hour characters in green lume, gold-tone hands, black world-time bezel with Greenwich in red, red bezel-lock crown at 2 o'clock, black strap, caseback with a gold snake emblem, red gift box; the description names the Seiko NH35 and an "ultra-dome LEXAN polycarbonate", and the spec table reads "Japanese GMT NH35 Automatic Winding Mechanism" (no GMT hand is fitted), 316L steel, LEXAN, 40mm, 15mm including the crystal, 100m; on sale on 2026-10-30. The listing's address ("aero-chinese-hour-2024-dark-red-dial-copy") suggests an earlier 2024 Chinese Hour edition, which is no longer in the store catalogue.
