The Reverso Q334818J, seen from the bench

The Reverso was introduced in 1931 as a sports watch with a reversible case to protect the dial during polo matches. The Q334818J model is powered by the Jaeger-LeCoultre 844 caliber with hour and minute indication. The case features 14mm lugs for the strap.

Frequently asked questions

What is the lug width of the Jaeger-LeCoultre Reverso Q334818J?

The lug width of the Jaeger-LeCoultre Reverso Q334818J is 14mm. Measurement is taken with a digital calliper between the lug pins at the contact point with the strap. This dimension is model-specific and determined by the compact 20mm case geometry.

Which strap do you recommend for the Reverso Q334818J?

For the Reverso Q334818J we recommend black alligator or brown vegetable-tanned leather for formal elegance, or robust calf leather for daily wear. Colour choice depends on your wardrobe: black for absolute timelessness, cognac brown for natural warmth, navy blue for personal signature whilst maintaining formality.

How do I change the strap on my Jaeger-LeCoultre Reverso Q334818J?

The strap is changed by removing the spring bars that connect the lugs to the case. Use a dedicated tool or small lever, releasing the spring-bar tension on one side to extract the pin. Reinsert the pin into the new strap, aligning it correctly in both lugs and ensuring it is firmly seated on both sides.

Can I use an aftermarket-compatible strap on my Reverso Q334818J?

Yes, any strap with 14mm lug width is compatible with the Q334818J, provided thickness does not exceed 3–3.5mm. Always verify compatibility before purchase by consulting technical datasheets. A quality aftermarket strap in alligator or calf leather can significantly enhance the watch while preserving its aesthetic integrity.

How long does a leather strap last on the Reverso Q334818J?

A quality leather strap with vegetable tanning lasts approximately 3–5 years with moderate use (not daily wear). If worn daily, natural leather will wear after 18–30 months. The patina developed is part of its charm. Casati Milano straps include an 18-month warranty against manufacturing defects.
