About this entry

74% of key specs known. Missing: weight, hardening, bracelet links, end links, link attachment.

Brand specs (one spec list for the 36mm GS, 39mm GX and 42mm GL): Miyota 9015, 316L, 36/39/42mm, 43.5/46.5/49.5mm lug-to-lug, 10.1mm including crystal for all three, 19/20/21mm lugs, sapphire with AR coating (side not stated), stainless steel bezel (fixed and smooth in the photos), gradient "Jian Zhan" dial with applied indices, hexagon logo and date window at 6, lumed bar hands, BGW-X1 blue lume on hands and markers, screw-down crown with hexagon logo, screw-down solid caseback, 100m, solid 316L bracelet with the "New Fly Adjustable Clasp" (on-the-fly; positions and range not stated). Weight and strap details are not stated. The brand says the dial is inspired by Jian Zhan, a Song dynasty porcelain, and describes a porcelain-style maker's stamp in seal script; no watch is named as a model, so inspired_by is left blank. The original listing (light blue, red and orange; the brand spells "Gardient") is $408 with no strap option and was sold out on 2026-10-25; the brand notes the orange and red dials have been changed to a lighter colour. The "new dial colors" listing (black, white, green, purple) is $368 on the rubber strap or $408 on the bracelet. The SN0144-GX-5 listing sells the same 39mm case and specs with a single porcelain-pattern dial at $368 on the rubber strap or $408 on the bracelet, both in stock on 2026-10-25. Stock on 2026-10-25 for the new colours: green in stock on both, the rest sold out. The 39mm case is also sold with the Miyota 90S5, 9075 (GMT) and 9132 (see the other sn0144-39mm files).
