Grand Seiko’s latest limited edition takes a quieter route than many of the brand’s recent releases.
The SBGW325 9S Mechanical Manual-Winding Limited Edition ‘Arabic Numerals’ swaps textured landscapes and overt craftsmanship cues for a crisp blue dial, compact proportions and numerals with real design history behind them.
It’s a watch aimed less at spectacle and more at the collector who enjoys the finer points of Grand Seiko’s visual language.

At a glance
- Grand Seiko has introduced the SBGW325, a 600-piece manual-winding limited edition with Arabic numerals.
- The watch features a matte blue dial, silver dauphine hands, a gold seconds hand and typography linked to designer Nobuhiro Kosugi.
- It is priced at £5,000 including VAT and is expected in the UK from October 2026.
A cleaner Grand Seiko with early-model roots
The SBGW325 looks back to the SBGW003, a 2001 model created for Seiko’s 120th anniversary.
That watch itself drew from the earliest Grand Seiko designs of 1960, when the young collection was still defining its idea of refinement through proportion, legibility and restrained finishing.
The new model keeps that lineage visible without turning into a period exercise.

At 37.3mm in diameter and 11.7mm thick, it sits in the sweet spot for collectors who prefer smaller, manually wound dress watches but don’t want something fragile or overly formal.
The stainless steel case uses polished surfaces across the bezel, caseband and lugs, giving the watch a more elevated feel than its spare dial might first suggest.
The Kosugi numerals and a sharper blue dial
The defining feature is the Arabic numeral set, originally created by Nobuhiro Kosugi, who led Grand Seiko design at the time of the SBGW003.

The numerals were drawn to sit naturally with the Grand Seiko logo, and that harmony matters here because there’s very little else on the dial to distract the eye.
A dot minute track, polished dauphine hands and matte blue surface give the watch a direct, highly legible character.
The silver hands and numerals keep the layout cool and precise, while the gold seconds hand echoes the GS logo and adds a small touch of warmth.

There’s a faint field-watch practicality to the composition, though the absence of lume and the 30-metre water resistance keep it firmly closer to dress-watch territory.
The indigo crocodile leather strap, described as ‘Japan Blue’, deepens the overall palette and is joined by an additional grey leather strap.
Manual winding suits the character
Inside is Grand Seiko’s calibre 9S64, a manual-winding movement with a 72-hour power reserve.
It runs at 28,800 vibrations per hour and is rated to a daily accuracy of +5 to -3 seconds.
In a period where Grand Seiko often draws attention with Spring Drive and hi-beat movements, the choice of a hand-wound mechanical calibre feels deliberately restrained.
That restraint works with the watch rather than against it.
The fluted crown also gives the daily ritual of winding and setting the time a practical dimension, which is part of the charm of a watch like this.
