Strap for Classic Date 37 Stainless Steel - Rose Gold / Silver / Bracelet

The Oris Classic 01 733 7578 4331-07 8 18 63 is equipped with 18-millimetre lugs. This width represents the correct standard for the 37mm case: visually proportioned and not excessive. When ordering a strap for this timepiece, always verify that the width is precisely 18mm to ensure a perfect fit between the lugs.

For the Oris Classic 01 733 7578 4331-07 8 18 63, the ideal strap depends on intended use. For formal elegance, we recommend alligator or crocodile leather crafted with vegetable tanning: the regular grain emphasises the watch's classical proportions. For daily versatility, vegetable-tanned calf leather (fine grain) offers solidity and a less formal aesthetic. NATO straps allow a contemporary reinterpretation whilst maintaining sobriety. For practicality without compromise, vulcanised rubber is the most durable choice.

The procedure requires specific tools: a spring bar tool or small flathead screwdriver. Position the watch on a clean, soft surface. Locate the lateral metal pins connecting the strap to the case (the spring bars), then apply gentle downward pressure with the tool to compress the internal spring. Extract the pin from one side, then remove the strap. Repeat the operation on the other side. Install the new strap by inserting the pins into the holes, ensuring they click into position with a distinct snap.

Absolutely. The Oris Classic 01 733 7578 4331-07 8 18 63 uses standard spring bars, compatible with any 18mm lug-width strap. An artisanal leather or rubber strap allows you to completely personalise your watch's character: you can transition from a formal look (alligator, shell cordovan) to a more casual proposal (NATO, rubber) in seconds. Simply ensure that the new strap has the correct shoulders for installation on your Oris's 18mm lugs.

A natural leather strap (vegetable-tanned calf, alligator, shell cordovan) fitted to the Oris Classic 01 733 7578 4331-07 8 18 63 typically lasts between 3 to 5 years with moderate daily use, extending to 7–10 years with careful maintenance. Determining factors include exposure to perspiration, moisture and UV rays. Vegetable-tanned leather develops a natural patina over time and improves aesthetically with age. To extend longevity, occasionally apply a nourishing balm specific to watch leather and remove the watch before prolonged water activities.
