Frequently asked questions
What is the lug width of the Jaeger-LeCoultre Reverso Q39334M4?
The lug width is precisely 20 mm. This width is calculated by Jaeger-LeCoultre to maintain ideal proportions for the 27.40 mm case. Always measure the distance between the two spring bars to verify compatibility with a new strap.
Which type of strap is most suitable for the Reverso Q39334M4?
Alligator is the most harmonious choice, as its uniform grain emphasises the formal purity of the case. However, vegetable-tanned leather develops a natural patina over time, whilst cordura or silk NATO straps provide daily versatility without compromising refinement.
How do you change the strap on a Jaeger-LeCoultre Reverso Q39334M4?
Use a spring bar tool to gently push the old strap's attachments inward. The spring bars will retract, freeing the lug. Align the new strap, insert the spring bars into the holes, and let them snap back into place. Verify that the strap is securely fitted before wearing the watch.
Is a quality aftermarket strap compatible with the Q39334M4?
Yes, provided the lug width is exactly 20 mm. MilanoStraps offers a curated selection of 20 mm straps already tested for compatibility with the Reverso and other Jaeger-LeCoultre models. Casati Milano personalises every strap according to your material, colour and clasp preferences.
How long does a natural leather strap last on a Reverso?
Durability depends on the material and usage. Superior-quality alligator or cordovan maintains integrity for 5–7 years of daily wear, whilst vegetable-tanned leather requires maintenance every 3–4 years but develops a beautiful patina. Natural rubber and cordura last longer. Casati Milano offers an 18-month warranty on manufacturing defects and recommends annual preventive maintenance.
