1832 L4.325.4.92.2— lug 15mm

The Longines 1832 L4.325.4.92.2 features a lug width of 15mm. This is a specific and non-standard measurement, taken from inner shoulder to inner shoulder of the case lugs. It is essential to verify this dimension before purchasing an aftermarket strap, as 15mm is not a commercially standard width.

The best strap depends on intended use. For formal elegance, we recommend alligator or vegetable-tanned calf, which enhance the discretion of the 30mm case. For versatile daily wear, vegetable-tanned shell cordovan develops rich patina over time. For maximum practicality, rubber finished with a steel deployante or a woven NATO represent functional choices without compromise.

Remove the watch from your wrist and locate the spring bars (pins) connecting the strap to the case. Using an appropriate tool (spring bar tool), carefully remove the pin from the first lug. Extract the old strap and insert the new one by aligning the lug holes with the pins. Press until you hear a 'click' indicating secure locking. Ensure the pin is fully seated to guarantee safety.

Yes, you can use aftermarket straps provided they are certified for 15mm lug width. On milanostraps.it you will find artisanal straps compatible with various materials (alligator, calf, shell cordovan, rubber, NATO). The Casati Milano atelier also produces bespoke straps with personalised leather selection and custom stitching thread.

A high-quality natural leather strap, with proper maintenance, lasts 3-5 years of daily wear. Longevity depends on exposure to weather, humidity and tanning quality. Vegetable-tanned shell cordovan straps develop patina over the years and can last more than 5 years if treated with care. Rubber straps generally have superior durability in mechanical wear contexts.
