About this entry
80% of key specs known. Missing: weight, hardening, AR coating.
Undone's 37mm field watch in a "tartaruga (tortoise) shaped" cushion case, "an UNDONE's first", released in 2020; this is the Time Module (Seiko) NH35A build. The Disney Terra GMT listings use the same 37mm case with an NH34 GMT and are a separate model. Spec table on the Red Edition, Blue Lagoon and Safari listings: Japanese TMI NH35A, 316L steel, double-dome sapphire crystal, 37mm excluding the crown, 12.8mm including the crystal, 5 ATM / 50m; the Daybreak listings give only the movement and 5 ATM / 50m, and their text gives the 37mm case, the sapphire crystal and a "42-hour power reserve" (TMI's figure is 41 hours). Watch Review Blog's December 2020 review of the Daybreak adds a 43mm lug-to-lug and a screw-down crown. The 20mm lug width is from the Daybreak Suede strap photo's file name ("20mm_Leather"). None of the dials has a date window. The Daybreak, Blue Lagoon and Safari caseback photos show a see-through back; the Red Edition's back is printed "RED EDITION". No weight or bezel details are published. The Daybreak and Red Edition were on sale on 2026-10-30; the Blue Lagoon and Safari were sold out. Editions. Daybreak (USD 295): black dial with Arabic numerals, a 13-24 inner ring and a triangle at 12, two-colour lume (blue numerals, green markers and hands); sold as the Terra Daybreak on a brown leather strap (no SKU shown) and the Terra Daybreak Suede on a tan suede strap (TRA-DBK-SUD); the Daybreak page repeats the Suede's strap sentence. Red Edition (listed 2024-03, TRA-RED-BLK, USD 340; "limited edition", size not given): black-coated case, black dial with red numerals and hands, green lume, black leather strap with red stitching. Terra II "Surf and Turf" (USD 325): Blue Lagoon (TRA-BLU-LGN; light blue "grenade" waffle dial, white rubber strap) and Safari (TRA-SAF-OLV; olive grenade dial, olive strap). UNDONE X POPEYE "Arabian Knight" (COL-POP-ARB-LPS, USD 499; sold out on 2026-10-30): Popeye swaps his corncob pipe for a shisha hookah on a blue gemstone-inspired dial with Eastern Arabic numerals, his arms as the hour and minute hands; polished steel case, navy leather strap, see-through caseback printed "Popeye Limited Edition 000/300" (300 pieces). UNDONE x Simple Union: Urushi (COL-SU3-URS, USD 445; sold out and tagged archive on 2026-10-30): after Japanese urushi lacquerware and maki-e decoration, a black enamel-painted Cali dial with gold-coloured paint emulating sprinkled gold powder and the kanji 無, 常, 苦 and 空, a dark leather strap (photo filed "strap_vin_gry_deep") and a see-through caseback. Both spec tables match this model's ("NH35A/ NH39", 316L steel, double-dome sapphire crystal, 37mm excluding the crown, 12.8mm including the crystal, 5 ATM / 50m), both side photos are filed "Terra_sil_caseside", and neither dial shows the NH39's open-heart aperture or 24-hour indicator.
