Measure your wrist with a tailor's tape or a piece of string, comfortably snug.

What I'm asked about the Ball Watch Engineer II DG2022A-SAJ-WH
What strap size does the Ball Watch Engineer II DG2022A-SAJ-WH take?
The Ball Watch Engineer II DG2022A-SAJ-WH needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Ball Watch Engineer II DG2022A-SAJ-WH 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 Ball Watch Engineer II DG2022A-SAJ-WH?
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 48 mm diver I go for a full-thickness strap, not a thin one.
Which strap do you recommend for the Ball Watch Engineer II DG2022A-SAJ-WH?
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.
