Fit & sizing notes for the Elegance SBGW301
- Width: buy 19mm straps. Tapered straps listed as 19/17mm or 19/15mm fit too; only the first number has to match. See strap sizes explained.
- Spring bars: 19mm long. We haven't confirmed the diameter for this model, so measure the old bar before buying replacements (spring bar sizes).
- Odd size: 19mm straps are harder to find; a 18mm strap fits with a small gap, but never go wider. Odd lug width options.
- Wrist fit: at 44.3mm lug-to-lug it should sit within the top of wrists from about 14.8cm up (rule of thumb: lug-to-lug under ~30% of wrist size). That's longer than 13% of the watches in our index. See what size watch suits your wrist.
- Strap thickness: at 11.7mm thick it's mid-thickness, so most straps suit it; padded leather and NATOs both balance well.

Grand Seiko Elegance SBGW301 — strap questions
What size strap does the Elegance SBGW301 take?
The Grand Seiko Elegance SBGW301 has a 19mm lug width, so you need a 19mm watch strap.
Will any 19mm strap fit the Elegance SBGW301?
Most will. Width is the main thing to match, but also check that the strap's spring-bar holes suit the bars, and that the strap is thin enough to clear the case between the lugs. A metal bracelet needs 19mm end-links made for this model.
What spring bar size does the Elegance SBGW301 use?
19mm long. We haven't confirmed the diameter for the Elegance SBGW301, so measure the original bar with calipers before buying replacements.
Is the Elegance SBGW301 good for strap swapping?
Yes. With standard 19mm spring-bar lugs, NATO, leather, rubber and mesh straps can all be fitted with a spring-bar tool.
