About this entry

73% of key specs known. Missing: case diameter, weight, hardening, crown.

Grade 3 titanium Turtle-style diver ("Version: 2K21"; the store tags it "6105 Turtle" and "SRP777"). Brand specs: titanium Grade 3 case and case back, "45.5mm (with crown)" (diameter without crown not stated, so it is left blank), 47.1mm lug-to-lug, 13.0mm, 22mm lugs, unidirectional bezel with aluminium insert and lume pip (the listing warns the insert colour may fade), sapphire with AR coating (side not stated), Japanese SuperLuminova C3 green lume, 200m. The spec block names a Hangzhou 2553A automatic (day-date), which matches the day-date window in the photos. The crown is not described, so screw-down is not recorded. The photographed case back is solid and notched like a screw-down back, engraved "100% titanium", "200M/660FT" and "HTS-H4", which may be a model code; it is not stated in the listing. Sold only on a waffle rubber strap with titanium pin buckle (the photos show black straps on the grey and black versions, blue on the blue and orange on the red). The listing text says "Dial: black, blue, silver" while the options are grey, black, blue and red; bezel colours are from the photos. $199 for all four (crossed-out $438), all in stock on 2026-10-21. Weight not stated. It is a separate model from the steel Sharkey Mini Turtle (316L, 47.7mm lug-to-lug, 13.3mm, ceramic insert) and from the Titanium Turtle 6105 (20mm lugs, 46.8mm lug-to-lug, ceramic insert, Hangzhou 2565A). First listed in the store in November 2021; no independent review found.
