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 |

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 Day-Date 68238
What strap size does the Rolex Day-Date 68238 take?
The Rolex Day-Date 68238 needs 17 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Rolex Day-Date 68238 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 Day-Date 68238?
Yes, in 17 mm leather. On a 31 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Rolex Day-Date 68238?
A 17 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.
Frequently asked questions
Where can I find a 17 mm strap for the Rolex Day-Date 68238?
The Milano Straps catalogue does not have a ready-made 17 mm collection. A strap for the Rolex Day-Date 68238 is made to measure at Casati Milano atelier.
