What I'm asked about the Tudor Black Bay 58 7939G1A0NRU-0001
What strap size does the Tudor Black Bay 58 7939G1A0NRU-0001 take?
The Tudor Black Bay 58 7939G1A0NRU-0001 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 Tudor Black Bay 58 7939G1A0NRU-0001 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 Tudor Black Bay 58 7939G1A0NRU-0001?
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 39 mm diver I go for a full-thickness strap, not a thin one.
Which strap do you recommend for the Tudor Black Bay 58 7939G1A0NRU-0001?
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.

Frequently asked questions
Which strap is best suited for the Tudor Black Bay 58 7939G1A0NRU-0001?
We recommend alligator straps with vegetable tanning (dark brown or cognac), shell cordovan for those desiring luxury and natural patina, or vegetable-tanned calf for daily versatility. For regular diving, FKM rubber or NATO cordura straps guarantee maximum water resistance.
Is an aftermarket strap compatible with the Tudor Black Bay 58 7939G1A0NRU-0001?
Yes, any strap with 20mm lug width is compatible with the Black Bay 58. Always verify specifications before purchasing. We recommend artisanal straps of premium quality, crafted with fine leather and finished with care, to preserve the watch's value and aesthetics.
How long does a leather strap last on the Tudor Black Bay 58?
A quality leather strap (alligator or shell cordovan) typically lasts 3-5 years with regular use, depending on care and moisture exposure. Leather requires periodic maintenance: avoid prolonged submersion, dry it after immersion, and apply protective balms every 6-12 months. Rubber straps last 5-7 years before requiring replacement.
