Spring bars Datejust 31 steel — 17mm × 1.8mm blind
€12,95
Set of two spring bars for Rolex Datejust 31 in steel with blind lugs, in tempered Swiss Standard steel. Size: 17mm between the lugs. Pin 1.8mm. Compatible with the Datejust 31 steel produced from the early 2000s onwards — modern version with sealed case, strap removal only from the side.
The 17mm × 1.8mm blind on the modern steel Datejust 31 is the specification of the contemporary line. More refined case, improved finishing, blind lugs for aesthetics and Rolex production standardisation. The pin remains 1.8mm — the Datejust specification, midway between the 1.5mm sport and the 2.0mm vintage. When a client brings in a blind steel DJ 31 for a strap, these are the spring bars.
The same spring bars on every blind steel Datejust 31.

Frequently asked questions
What size are these spring bars?
17mm between the lugs, 1.8mm pin. They are made of hardened Swiss Standard steel, two pieces per set.
Will they fit my Datejust 31?
If it has the modern case with blind lugs, yes. We're referring to steel Datejust 31 models produced from the early 2000s onward, where the strap can only be removed from the side.
Why 1.8mm and not 1.5mm or 2.0mm?
The 1.8mm pin is the specification for the Datejust line. It falls between the 1.5mm of sport models and the 2.0mm of vintage models.
Do blind lugs change anything about fitting the strap?
Yes. With blind lugs, the strap can only be removed from the side, not from above. The spring bars remain the same for every steel Datejust 31 with this case.
Are these the original Rolex spring bars?
These are hardened Swiss Standard steel spring bars, designed to match the size and fit of the modern Datejust 31 case. The set consists of two pieces, measuring 17mm × 1.8mm.
