Strap for Big Crown Pointer Date 38 Calibre 473 Stainless Steel / Blue

The lug width of this model is 19.00 millimetres. This is a non-standard dimension, so it is essential to verify compatibility before purchasing an aftermarket strap. The measurement should be taken internally between the two lugs of the case, in a perpendicular position, without applying pressure to the spring mechanism.

For this aviation-inspired timepiece, we recommend three primary options: (1) alligator or shell cordovan leather for formal contexts, which enhance the proportion of the 38mm case; (2) NATO strap in ballistic nylon or canvas for a sporty, authentic approach; (3) vulcanised rubber for a pure instrument aesthetic. Each choice interacts differently with the oversized crown and satin-finished steel case.

Strap replacement requires a specific tool: a spring bar tool to extract the retention pins. Proceed carefully, inserting the flat tip between the strap and the case lug, releasing the tension of the internal spring. Once the old strap is removed, insert the new one by aligning the pins precisely, ensuring the spring mechanism is correctly positioned. If uncertain, consult a specialised watchmaker.

Yes, although 19mm is a less common dimension compared to 18mm or 20mm, there are specialised suppliers offering high-quality straps in this size. Milano Straps maintains a dedicated 19mm collection, including Italian leather with vegetable tanning, hand-dyed NATO straps, and natural rubber. The artisanal construction quality ensures precise lugs and certain compatibility with the original Oris spring bars.

A quality leather strap—such as alligator, shell cordovan, or vegetable-tanned calf—has a lifespan of 4–7 years with regular use, varying based on climate conditions, frequency of wear, and maintenance. The leather will develop a natural patina over the first 18 months, a sign of positive ageing. To extend durability, store the watch in a dry environment and periodically apply leather-specific conditioners. A NATO strap offers greater longevity, often exceeding 10 years, thanks to the resilience of ballistic nylon.
