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 | 120 / 70 mm |
| 16.5–17.8 cm | 125 / 75 mm |
| 17.9–19.0 cm | 130 / 80 mm |
| 19.1–20.3 cm | 135 / 85 mm |
| 20.4–21.6 cm | 140 / 85 mm |
| 21.7–22.9 cm | 145 / 90 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 Oris TT3 01 774 7611 7784-Set
What strap size does the Oris TT3 01 774 7611 7784-Set take?
The Oris TT3 01 774 7611 7784-Set needs 28 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Oris TT3 01 774 7611 7784-Set 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 Oris TT3 01 774 7611 7784-Set?
Yes, in 28 mm leather. On a 46 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Oris TT3 01 774 7611 7784-Set?
A 28 mm box calf. 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.
