Titanium GMT diver with a helium escape valve and "Titanium-Yacht" on the dial. Thorn uses the code SHY037 (title, spec list and SKU) both for this NH34 GMT and for a no-date NH35 titanium Submariner-style diver in the same 40.5mm x 48mm x 14mm, 300m case, published as SHY037 (NH35). Brand specs: Seiko NH34A automatic GMT (hours, minutes, seconds, date, GMT), titanium case (grade not stated), solid screw-down titanium caseback, unidirectional ceramic bezel, double-domed sapphire with AR coating (side not stated), 300m, helium escape valve, "high-visibility luminous dial" (lume grade not stated), titanium bracelet with quick-release system, folding clasp with micro-adjustment holes, 40.5mm, 48mm lug-to-lug, 14mm thick (whether that includes the crystal is not stated). The text gives the bezel a 24-hour GMT scale, but the photos show a 60-minute bezel with the 24-hour scale on the dial's inner ring, so the bezel scale is left out. Crown type and lug width are not stated. Price $229 (crossed-out $259). First listed on Thorn's store in December 2023.
