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 Rolex Sea-Dweller 126600
What strap size does the Rolex Sea-Dweller 126600 take?
The Rolex Sea-Dweller 126600 needs 21 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Rolex Sea-Dweller 126600 be changed?
Yes, and easily: the lugs are drilled, so the spring bar is pushed out from the outside with a thin pin, without opening anything. If you prefer, I do it in the workshop.
Can I put a leather strap on the Rolex Sea-Dweller 126600?
Yes, in 21 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 43 mm diver I go for a full-thickness strap, not a thin one. I don't keep rubber ready in 21 mm: write to me and I'll make it.
Which strap do you recommend for the Rolex Sea-Dweller 126600?
Rubber if you wear it in the water; otherwise a 21 mm calf strap, full thickness. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
