Spring bars Rolex Submariner 6538 — 20mm Big Crown
€12,95
Set of two spring bars for Rolex Submariner reference 6538, in hardened Swiss Standard steel. Size: 20mm between the lugs. Pin 2.0mm. Drilled lugs. The 6538 is the Big Crown Submariner produced from 1956 to 1959 — four years of production, a few thousand pieces, the watch worn by James Bond in Dr. No.
The 6538 has the 8mm crown — Big Crown, hence the name — and a case that is practically identical to the 5510 and 6536/1 of the same era. For the strap, the geometry is that of the first Submariner family: 20mm lug, through-hole, 2.0mm pin. On an original 6538 you do not fit a strap at random: the case is nearly seventy years old and every detail matters.
The same piece I fit on the 6538s of my collector clients. The same supplier.

Frequently asked questions
What size are these spring bars?
20mm between the lugs, 2.0mm pin. This is the size of the 6538, the same geometry as the first Submariner family.
Do they also fit other vintage Submariners?
The 6538 case is practically identical to that of the 5510 and the 6536/1 from the same period, with the same 20mm lug and the same 2.0mm pin. To be sure about your specific watch, feel free to write to me.
Are the lugs drilled or closed?
Drilled. On this type of case, fitting is done through the hole, not by pressure.
What material are they made of?
Hardened Swiss Standard steel. The same piece I fit on collectors' 6538 watches, from the same supplier.
Are they suitable for an original vintage piece?
Yes, the size follows the original geometry of the 6538: 20mm, 2.0mm pin, drilled lugs. On a case that's nearly seventy years old, every millimetre counts, and these are designed exactly for that.
