Strap for Frank Sinatra Small Second Date Stainless Steel / Silver / Bracelet

The lug width is 19.00 millimetres. This dimension is specific to this model and was selected by Oris to maintain elegant proportions on a 39-millimetre case. It is essential to verify that any compatible strap has exactly 19 millimetres of internal lug width.

Choice depends on usage and aesthetic preference. For formal contexts, an alligator strap in black or navy blue with vegetable tanning enhances the swing heritage of the piece. For everyday versatility, natural vegetable-tanned calf leather in cognac or off-white tones offers balance between elegance and practicality. For a sporty-casual style, a NATO strap in charcoal grey or tobacco communicates immediacy without stylistic compromise.

Use a spring bar tool or fine-pointed instrument to apply controlled pressure on the internal spring mechanism of the lug. Position the watch on a soft cloth to protect the crystal. Compress the spring slightly whilst removing the old strap, then align the holes of the new strap with the lugs and release the spring. Verify that the lug is properly anchored before wearing the watch.

All straps with a 19-millimetre lug width are compatible. It is essential to verify the internal measurement between the lugs using a digital calliper before purchase. Artisanal straps from milanostraps.it are tested specifically on this Oris reference and guarantee fit without excessive play or visual undulation.

Durability depends on material and usage. A vegetable-tanned alligator strap, with normal care, lasts 3-5 years before showing visible signs of wear. Vegetable-tanned calf leather has similar longevity but is more resistant to accidental marking. Avoid prolonged water immersion, direct intense sunlight exposure, and excessive bending. Periodic maintenance with specific balms significantly extends the longevity of the piece.
