FAQ
What is the lug width of the Jaeger-LeCoultre Master 6006405 (Q6006405)?
The Jaeger-LeCoultre Master 6006405 (Q6006405) is fitted with a 20mm lug width. This measurement is verified by inserting a millimeter caliper between the two lower lugs of the case: the internal distance between the lugs precisely indicates the strap width to be installed. An incorrectly sized strap will not fit properly and may damage the attachment pins.
What is the best strap for the Jaeger-LeCoultre Master 6006405 (Q6006405)?
For a platinum watch with tourbillon and perpetual calendar such as the 6006405, the most coherent strap is louisiana alligator belly-cut, with fine and symmetrical grain. The crocodile complements the case finishing without overwhelming it. Box-calf leather is a more understated alternative for formal occasions. In both cases, the correct lug width is 20mm and the buckle should be in platinum or white gold for color consistency.
How do you change the strap on the Jaeger-LeCoultre Master 6006405 (Q6006405)?
The 6006405 strap is replaced using a specialized spring bar tool. The spring pins that connect the strap to the lugs of the platinum case are compressed laterally to release the strap. It is recommended to entrust this task to a watchmaker or specialized atelier such as Casati Milano to avoid scratches on the platinum case, a material particularly prone to surface marks.
Are there aftermarket straps compatible with the Jaeger-LeCoultre Master 6006405 (Q6006405)?
Yes: any strap with a 20mm lug width is technically compatible with the Jaeger-LeCoultre 6006405. On milanostraps.it you will find a selection of artisanal 20mm straps in alligator, leather, and other materials, crafted by Casati Milano with quality standards consistent with Haute Horlogerie. High-quality aftermarket straps can match—and in some cases exceed—original options in terms of customization and longevity.
How long does a leather strap last on a Jaeger-LeCoultre Master 6006405 (Q6006405)?
The lifespan of a leather strap depends on the material, usage, and care. A quality alligator strap with hand stitching and finished edges typically lasts between 2 to 5 years with daily use. Calf leather tends to soften more quickly with perspiration, while crocodile is more resistant to moisture. Casati Milano offers an 18-month warranty against manufacturing defects. To extend strap life, it is recommended to avoid prolonged water contact and to rotate multiple straps in use.
