Lug width to be confirmed

On this Longines HydroConquest L3.247.0.87.6 the lug width doesn't convince me, and I don't want to give you a number I'm not sure about. Write to me on WhatsApp with the reference or a photo of the watch: I'll check it and tell you myself.

Frequently asked questions

What is the best strap for the Longines HydroConquest L3.247.0.87.6?

The best strap depends on the intended use. For elegance and versatility, an alligator strap with vegetable tanning in caramel brown with cream stitching provides harmony with the blue dial. For sportiness, a NATO strap in heavy cotton navy or grey creates contemporary contrast. For actual diving, an FKM rubber strap in black with waffle texture ensures grip and rapid drying. Your choice should balance the aesthetic and functional character of the watch.

How long does a leather strap last on the Longines HydroConquest L3.247.0.87.6?

A quality leather strap, crafted with vegetable tanning and premium materials such as alligator or shell cordovan, typically lasts 3-5 years with daily wear, developing an increasingly beautiful patina over time. Longevity depends on water exposure, humidity, frequency of wear, and care. A calf leather strap tends to show visible wear within 2-3 years. The 18-month warranty provided by Casati Milano covers manufacturing defects and demonstrates commitment to longevity.
