The Grand Seiko “Cheng Quan” SBGW327G is a 99-piece mainland-China edition built around a 36.5mm modern 44GS case, a light-blue spring-water dial and the hand-wound 9S64 movement. The compact proportions and three-day reserve make it more than a dial swap, but there is no confirmed UAE allocation.
Grand Seiko Shanghai lists sales from 1 October 2026 through its Shanghai boutique and official online direct store. WristBear has not handled or stocked this reference, so the fit and colour comments below are sourced analysis rather than a wrist test.

The dial does spring water without turning vague
Cheng Quan translates to clear spring water. The dial uses a very pale blue surface with a texture that spreads outward from the centre like ripples. Rose-gold-coloured treatment on the GS logo and seconds hand provides a small warm contrast. The hour and minute hands stay silver, so the dial does not become a two-tone costume.
The elephant-grey leather strap is stitched in light blue to repeat the dial colour. It is a more coherent choice than simply fitting another blue strap, although the unusual combination will be harder to judge from photographs than a conventional black or navy dial.
What changed
- The light-blue textured dial takes its cue from clear spring water.
- Rose-gold-coloured details warm the GS logo and seconds hand.
- The grey leather strap adds light-blue stitching that repeats the dial colour.
What stayed the same
- The 36.5mm faceted steel case uses Grand Seiko’s modern 44GS design language.
- Calibre 9S64 remains a three-day hand-wound movement with hacking seconds.
- Box-shaped sapphire crystal and 10-bar water resistance keep the compact case practical.
The 36.5mm case is the practical headline
The stainless-steel case measures 36.5mm across and 11.55mm thick, with an 18mm lug width. Grand Seiko Shanghai describes the faceted design as a 44GS case form, with wide flat planes and distortion-free mirror polishing intended to catch light cleanly.
A box-shaped sapphire crystal with anti-reflective coating sits above the dial. The stated 10-bar water-resistance rating is unusually useful for a leather-strap dress watch, though the leather itself still deserves ordinary restraint around water. A three-fold push-button clasp closes the strap.
9S64 keeps the watch deliberately manual
Calibre 9S64 is hand wound, runs at 28,800 vibrations per hour and uses 24 jewels. A full wind provides approximately 72 hours of reserve, and hacking seconds lets the wearer stop the seconds hand while setting the time.
Grand Seiko states a mean daily rate of +5 to -3 seconds for the uncased movement under controlled testing and a normal-use range of +10 to -1 seconds per day. Those are separate figures, not a promise that every watch will run within the tighter bench-test range on the wrist.
The practical read The dial is the headline, but the 36.5mm case and three-day manual movement are the substance. The catch is simple: this is a 99-piece mainland-China release with no confirmed UAE allocation.
Mainland-China price and UAE availability
Grand Seiko Shanghai’s press information sets the suggested mainland-China retail price at CNY 42,500. Using the dated CNY/AED reference rate retrieved for this release, that is about AED 23,242.79. This is an indicative currency conversion, not official UAE retail, landed cost or a discount.
The release is limited to 99 numbered watches for mainland China, excluding Hong Kong, Macau and Taiwan. WristBear stock and UAE availability are unconfirmed.
Verdict: choose SBGW327G for the compact 44GS case
The SBGW327G is for someone who wants Grand Seiko’s sharp 44GS geometry without a 40mm case, and who sees manual winding as part of the appeal rather than an inconvenience. The spring-water dial gives the watch its identity, but the 36.5mm dimensions and three-day 9S64 are the reasons the design should remain wearable after the novelty wears off.
If local service, easy availability or trying the watch on first matters, wait. Ninety-nine China-only pieces make this a poor candidate for pretending there is a straightforward UAE buying route.
