Ostrich Leg Strap for the Seiko SNS003: Extra-Long
This order out of Texas named its watch precisely — Seiko SNS003, caseback reference 5R64-0AA0 — and asked for two things that rarely come together off the shelf: an ostrich leg strap for the Seiko SNS003 in dark brown, and an extra-long 90/145mm cut.
The build

Why these choices
A double reference like this is the best thing a custom order can carry. The model number plus the movement code pin the strap to one specific watch, so there is no guessing at the case end — useful on older Seiko references, where a name alone can cover several dial and case variants.
Ostrich leg is the scaled section of the hide, not the body leather most people picture. There are no quill bumps; instead the surface runs in natural scale plates that vary across the strap, so no two cuts repeat. In dark brown it reads as a textured dress strap — more presence than smooth calf, less flash than crocodile. The rest of the family lives in our ostrich leather straps collection, and this exact leather is the dark brown ostrich leg strap.
The 90/145mm length is our extra-long build, which covers wrists from 8.5 in to 12 in (roughly 216–305mm). Most makers stop at 8.5 in, which is exactly why these orders reach us: the watch fits, the strap never did. Regular tool-fitted spring bars and a plain stainless buckle keep the hardware quiet under a textured leather.

“Wonderful quality strap that does my grandfather’s old watch justice.”

Frequently asked questions
Do you make an ostrich leg strap for the Seiko SNS003?
Yes — the strap in this post is that exact build, at 90/145mm. Give us your model reference and, if you have it, the caseback code, and choose your length in the configurator; standard and extra-long cuts use the same leather.
What is the difference between ostrich and ostrich leg leather?
Body ostrich carries the familiar quill bumps left by feather follicles. Ostrich leg is the leg section: flat natural scale plates in place of quills, with a pattern that shifts along the strap.
