What I'm asked about the Rolex Submariner 6204

What strap size does the Rolex Submariner 6204 take?

The Rolex Submariner 6204 needs 19 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 Rolex Submariner 6204 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 Submariner 6204?

Yes, in 19 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 37 mm diver I go for a full-thickness strap, not a thin one. I don't keep rubber ready in 19 mm: write to me and I'll make it.

Which strap do you recommend for the Rolex Submariner 6204?

Rubber if you wear it in the water; otherwise a 19 mm calf strap, full thickness. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
