FAQ

What is the lug width of the Longines Lyre L4.359.4.72.6?

The lug width is 16 millimetres. This dimension is specific to the 32mm Lyre models and is determined by the distance between the case attachment pins. A compatible strap must be exactly 16mm wide to ensure proper fit and stability on the wrist.

Which strap is best for the Longines Lyre L4.359.4.72.6?

The ideal strap depends on the intended use. For a formal setting, an alligator or vegetable-tanned calfskin strap in neutral tones enhances the piece's minimalist elegance. In summer, a rubber or silicone strap maintains sophistication without sacrificing practicality. Shell cordovan is the choice for those who appreciate a material that ages beautifully over time.

How do I change the strap on a Longines Lyre L4.359.4.72.6?

Use a spring bar tool to gently compress the small springs that hold the pins. Insert the tool into the notch between the case and strap, compress the pin until it disengages, then remove the pin. Repeat on the other side. To fit the new 16mm strap, align the holes and insert the pin until it clicks into place.

Are aftermarket straps compatible with the Longines Lyre L4.359.4.72.6?

Yes, absolutely. The 16mm lug width is a standard shared by many watchmakers and specialist manufacturers. Aftermarket straps in alligator, calfskin, cordovan and rubber are fully compatible, provided they meet the 16mm specification. Online you will find a wide range of customisable straps in colour, thread and initials.

How long does a leather strap last on a Longines Lyre L4.359.4.72.6?

Durability varies depending on the material and usage. Vegetable-tanned calfskin typically lasts 4-7 years of daily wear, developing a unique patina. Alligator is more durable and can last 8-10 years. Rubber resists for 5-8 years before losing elasticity. Factors such as humidity, perspiration and maintenance affect longevity. Regular care with specific balms significantly extends useful life.
