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 |

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 Prospex Divers SBDC039
What strap size does the Seiko Prospex Divers SBDC039 take?
The Seiko Prospex Divers SBDC039 needs 20 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Seiko Prospex Divers SBDC039 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 Prospex Divers SBDC039?
Yes, in 20 mm leather, as long as you don't wear it in the water: leather doesn't like the sea or the pool. For days in the water, rubber. On a 45 mm diver I go for a full-thickness strap, not a thin one.
Which strap do you recommend for the Seiko Prospex Divers SBDC039?
Rubber if you wear it in the water; otherwise a 20 mm calf strap, full thickness. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
