Lug width

What length do I need?
Measure your wrist with a tailor's tape or a piece of string, comfortably snug.
| Wrist circumference | Length (long side / short side) |
|---|---|
| 15.0–16.4 cm | 110 / 70 mm |
| 16.5–17.8 cm | 115 / 75 mm |
| 17.9–19.0 cm | 120 / 80 mm |
| 19.1–20.4 cm | 125 / 80 mm |
| 20.5–21.6 cm | 130 / 85 mm |
| 21.7–22.9 cm | 135 / 85 mm |
| over 22.9 cm | on request |
The ready-to-wear strap is 115 × 75 mm. For a smaller or larger wrist I make it in the right length: order your length.
What I'm asked about the Seiko Essentials SWR078P
What strap size does the Seiko Essentials SWR078P take?
The Seiko Essentials SWR078P needs 15 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Seiko Essentials SWR078P be changed?
Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.
Can I put a leather strap on the Seiko Essentials SWR078P?
Yes, in 15 mm leather. On a case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Seiko Essentials SWR078P?
A 15 mm calf strap, for every day. I don't keep this size ready in the catalogue: I make it to measure. If you'd rather have something built on your wrist, the Casati atelier.
