Strap for Streamliner Flyback Undefeated

The lug width (ansa width) of the H. Moser & Cie Streamliner 6902-1206 is 20mm. This measurement refers to the distance between the attachment pins on the case. It is essential to verify this dimension before purchasing an aftermarket strap, as an incorrect lug width will not fit properly and may damage the watch pins during installation.

For the Streamliner 6902-1206, the most appropriate materials are alligator with vegetable tanning, shell cordovan, and anilina calf leather. Alligator offers a natural scale texture and a patina that evolves over time. Shell cordovan is more compact and durable, ideal for those seeking superior longevity. For daily rigorous use or sporting environments, a NATO strap in ballistic nylon or vulcanised rubber represents a practical and versatile alternative without compromising the minimalist elegance of the Swiss chronograph.

The Streamliner 6902-1206 strap is changed by extracting the attachment pins from the case (those that pass through the lug at the 20mm width). Use a specialised pin removal tool, available from jewellers and specialist watchmakers. Position the watch on a protected surface, press the pin downward and slide it laterally until fully extracted. The old strap is then free and the new strap can be inserted, ensuring the pins enter correctly on both sides of the case. Never force the pins: if they resist, verify that the strap is perfectly aligned.

The Streamliner 6902-1206 is compatible with any quality strap with a 20mm lug width. Among the aftermarket options of excellence are alligator and shell cordovan straps from European specialist manufacturers, NATO straps in ballistic canvas from Scandinavian and British producers, and vulcanised rubber straps from Italian and German companies. Milano Straps offers a carefully curated selection of 20mm straps, customisable in leather, NATO and rubber, ready for dispatch.

The lifespan of a leather strap depends on the material, tanning and use. An alligator or calf strap with vegetable tanning lasts on average 3-5 years with moderate daily use. Shell cordovan, thanks to its natural compactness, can last 5-7 years. Frequency of use, exposure to sunlight and moisture, as well as the quality of maintenance (regular cleaning, drying after moisture contact), significantly influence longevity. A NATO strap, not being exposed to the natural ageing of leather, maintains its mechanical properties for 4-6 years, unless damaged by external abuse.
