From the SKX and Turtle divers to the Presage and Alpinist, Seiko watches are some of the easiest to transform with a leather strap. Most popular Seiko models take a 20 mm or 22 mm strap, and every Gracie USA strap is cut to your exact lug width and wrist size.
Seiko lug widths by model
The lug width is the gap between the two lugs where the strap attaches. Common Seiko references:
| Seiko model | Lug width |
|---|---|
| SKX007 / SKX009 | 22 mm |
| Prospex "Turtle" (SRP777 family) | 22 mm |
| Seiko 5 Sports (42.5 mm) | 22 mm |
| Presage Cocktail Time (40.5 mm) | 20 mm |
| Alpinist (39.5 mm, SPB121 family) | 20 mm |
| SARB033 / SARB035 | 20 mm |
Sizes are for current or common references. Older and limited references can differ, so measure between the lugs with a ruler or caliper, or email support@shopgracieusa.com with your reference number and we will confirm the size.
Choosing a leather for your Seiko
Seiko divers look great on a padded calfskin or a racing strap with contrast stitching; the Presage and Alpinist suit smooth Swift, alligator or a green leather that echoes the dial.
How we make your strap
Each strap is cut and saddle-stitched by hand in our Saigon atelier, made to your lug width (12–24 mm) and wrist size, and fitted with quick-release spring bars. Choose a pin buckle or a butterfly (deployant) clasp, curved ends, padding and contrast stitching. Processing takes 5–10 business days; U.S. shipping is free and every order has 30-day returns.
Seiko strap questions
Will a Gracie USA strap fit my Seiko?
Yes, if your watch has standard lugs with spring bars. Choose your lug width when you order; we cut the strap to that size.
Can I keep my original Seiko buckle?
Every strap comes with its own buckle or clasp. Many customers fit their original buckle instead; tell us the buckle width at checkout so we make the strap end to match.
Is this an official Seiko product?
No. Gracie USA straps are aftermarket accessories, not affiliated with or endorsed by Seiko. The brand name is used only to describe compatibility.
