Strap for Streamliner Flyback Automatic Stainless Steel / Grey

The lug width of the 6902-1200 is 20mm. This dimension represents the contemporary standard for luxury chronographs and accommodates a wide variety of aftermarket straps in leather, fabric, and rubber. To verify compatibility, measure the distance between the centres of the lugs on the case: this must match the nominal width of the strap you intend to purchase.

There is no single 'best strap'—it depends on your usage. For refined sporting elegance, we recommend vegetable-tanned calf leather in dark brown or cognac tones, which softens the geometric character of the case. To maintain the chronographic vocation, a black polyamide NATO remains the most versatile choice. For sophistication, a black polished alligator strap with a stainless-steel deployante clasp is unmatched. A rubber FKM strap is ideal for aquatic environments and intensive use.

The Streamliner, like most modern sports timepieces, features lugs fitted with spring bars. To change the strap: gently push the pins inward using a small tool (strap removal lever or ballpoint pen) until the spring ends release downward. Align the new strap holes with the lug pins and push until the click indicates secure seating. Verify firmness before wearing the watch.

Yes, provided they have the correct lug width (20mm). Quality aftermarket straps are fully compatible: brands like Milano Straps offer straps specifically for this width in leather, alligator, shell cordovan, NATO, and rubber. It is important to verify measurements before purchase to avoid lateral movement or excessive tension on the case lugs.

The lifespan of a leather strap for the 6902-1200 depends on leather quality and intensity of use. Good-quality vegetable-tanned calf leather, with thickness of 1.4–1.6mm, typically lasts 18–36 months of moderate daily wear. Shell cordovan, being denser and more resistant, can last 3–5 years. Regular maintenance (drying after water contact, cleaning with a soft cloth) significantly extends strap life. Wear is an interesting aesthetic process: leather develops patina and chromatic changes that narrate the object's history.
