Master Control 1548171— lug 20mm

The Jaeger-LeCoultre Master Control ref. 1548171 is fitted with a 20mm lug width strap. This measurement is taken with a caliper between the two lugs of the case at the strap attachment point. All 20mm straps are compatible with this reference.

For the Master Control 1548171, an alligator strap with Mississippiensis grain is the most appropriate choice given the watch's dress watch vocation. Smooth calf leather in black or tobacco brown is a more understated alternative, while vulcanized rubber is recommended for daily wear in less formal settings. The choice depends on your intended use and desired color coordination.

The Master Control 1548171 strap is secured with standard 20mm spring bars. To replace it, you only need a spring bar tool: insert the tip into the spring bar slot, compress the spring, and remove the bar from the lug. This operation does not require specialized tools, but it is advisable to perform it on a soft surface to protect the case from potential scratches.

Yes, the Master Control 1548171 is fitted with a 20mm lug width and standard spring bars, making it fully compatible with all quality aftermarket straps produced in this size. Milano Straps offers a selection of handcrafted leather, alligator, calf, rubber, and NATO straps compatible with this reference, made by the Casati Milano atelier.

The lifespan of a leather strap depends on the quality of the leather, the craftsmanship, and the intensity of use. A high-quality handcrafted alligator or calf strap, such as those produced by Casati Milano, can last 3 to 5 years with regular use, provided prolonged contact with water and sweat is avoided. The 18-month warranty on manufacturing defects offered by Casati Milano covers any issues related to craftsmanship.
