Frequently asked questions
What is the lug width of the Omega Speedmaster Broad Arrow 3653.80.33?
The Omega Speedmaster Broad Arrow 3653.80.33 features a 20mm lug width. This measurement is the standard reference for straps and bracelets compatible with this model. Always verify the lug width (the connection between case and strap) before purchasing a new strap.
Which strap is best suited for the Omega Speedmaster Broad Arrow in red gold?
For the 18k red gold, we recommend alligator leather in hazelnut or dark brown tones, or Cordovan calf in burgundy. These noble materials dialogue with the warmth of the precious metal and convey elegance without obscuring the design. In summer, a black rubber or earth-toned NATO strap remain functional and refined choices.
How do you change the strap on the Omega Speedmaster Broad Arrow 3653.80.33?
Proceed with a spring bar tool or dedicated instrument. Position the watch on a soft surface, locate the small lugs on the case sides, gently remove the spring bar retaining spring by pushing it inward with the tool. Once freed, slide off the old strap and insert the new one by snapping the spring into the designated slots. Avoid forcing to prevent damaging the lugs.
Can I fit an aftermarket strap on this Omega?
Yes, provided it respects the 20mm lug width. Milanostraps offers handcrafted personalizable straps specifically for this dimension, with choice of leather, stitch finish and custom sizes. Every strap is tested for compatibility with the Broad Arrow.
How long does a leather strap last before needing replacement?
A quality leather strap, worn daily, maintains its aesthetic and structural characteristics between 18 and 36 months, depending on the leather type (alligator more durable than calf), climate conditions and maintenance. The patina that develops is not deterioration, but aesthetic enrichment. With proper care and protection from excessive moisture, wear remains cosmetic rather than functional.
