About this entry

63% of key specs known. Missing: water resistance, hardening, crown, bracelet links, end links, link attachment, clasp micro-adjust.

The diver-bezel model of Thorn's "1957 Tribute" T026 listing, which also sells the T026A (smooth bezel, PT5000) and T026C (Ronda 5030.D chronograph) as separate models, and all three as a "T026D" set ($619, crossed-out $637, with a leather watch box). Brand specs, given once for all three: PT5000 automatic, 316L case and bracelet (brushed and polished), domed sapphire with inner AR coating, C3 vintage Super-LumiNova on hands and indices, 38mm, 47mm lug-to-lug, 12.3mm including the crystal, 19mm band, 190mm band length, 136g (what was weighed is not stated), solid bracelet with quick-release spring bars and a solid micro-adjust clasp (micro-adjust type not stated). Water resistance is given only as "100m/200m (splash-proof / daily use)" without saying which model gets which, so it is left blank. The black bezel with a 60-minute scale is from the photos; its direction, clicks and insert material are not stated. Crown and caseback are not described. The photos show a black dial with no date window, so the PT5000's date is recorded as hidden. Price $189 (crossed-out $209). First listed on Thorn's store in November 2025.
