About this entry
87% of key specs known. Missing: movement, hardening.
The SN027-T2 listing (an "original design" limited-edition diver) sells a Grade 5 titanium case with a Seagull ST2146 at $435 or a ETA 2836 at $690 (sn027-eta-2836), in gray or black at the same price per movement. No spec sheet or reference entry for a Seagull ST2146 could be found, so there is no movement file and only the movement type is recorded; complications are taken from the dial. Brand specs: GR5 titanium, 43mm without crown, 51mm lug-to-lug, 12.5mm including crystal, 22mm lugs, sapphire with AR coating (side not stated), titanium bezel with a luminous scale (60-minute in the photos; direction not stated, though the SN027-T3 listing calls its bezel unidirectional), sandwich dial with "double date window" (the photos show a day window below 12 and a date window at 3), lumed hands, BGW-9 lume glowing blue, screw-in crown, screw-in titanium caseback, shark leather strap with pin buckle, 200m, about 86g (not stated what was weighed). The listing warns its figures may contain hand-measurement errors. Same case as the SN027-T1 (sn027-pt5000) and T3 (sn027-st2100) in the photos. Limited edition per the title; the edition size is not stated. Every variation showed "Out of stock" on 2026-10-24.
