Strap for Big Crown Date Swiss Hunter Team PS Edition / Bracelet

The lug width of the Oris Big Crown 01 733 7629 4063-Set MB is 22mm. This measurement corresponds to the distance between the lugs (the metal pins connecting the case to the strap attachments). To verify it, use a digital calliper positioned directly on the case lugs. A strap cut to exactly 22mm will fit perfectly without lateral play or instability.

The ideal strap depends on your usage: for formal occasions, we recommend vegetable-tanned Tuscan leather (Aged Tobacco) or alligator, which enhance the Big Crown's heritage character; for everyday practicality, a robust NATO or vulcanised rubber offer durability and ease of changeover. Traditionally tanned calf develops a natural patina that complements the brushed steel case magnificently, telling a story of wear.

Use a spring bar removal tool (small elastic rods that secure the strap to the lugs). Position yourself on the side of the strap opposite the lug, push inward to compress the internal spring, then extract the bar from the lug holes. Repeat on the other end. Insert the new spring bars through the lug holes of the new strap, align with the case lugs and snap them into position. Steady hands and precise movements prevent damage.

Yes, any strap with a 22mm lug width is compatible. Milano Straps offers a specialised collection of 22mm straps in leather, alligator, shell cordovan, NATO and rubber, all handcrafted and fully customisable. It is essential that the strap is cut precisely to 22mm to avoid lateral movement: manufacturing precision guarantees a flawless fit to the case.

A vegetable-tanned leather strap typically lasts 3-5 years with daily wear, considering natural wear patterns. Longevity increases if the strap is rotated with others: alternation allows the leather to breathe and stabilise after each wear, reducing mechanical stress. Vegetable tanning develops a fascinating patina over time, improving aesthetically despite signs of original structure. A well-made strap can remain in acceptable condition beyond 5 years, whilst showing noble signs of ageing.
