Strap for Streamliner Centre Seconds Stainless Steel / Green

The H. Moser & Cie Streamliner 6200-1200 features an 18mm lug width. This specification is standard across the Streamliner collection and allows access to a wide range of compatible aftermarket leather and fabric straps. To verify the correct measurement, measure the space between the case lugs: it must be exactly 18mm.

For the Streamliner 6200-1200, we recommend alligator or vegetable-tanned calf leather straps for formal wear, or shell cordovan for longevity and natural patina development. For everyday versatility, robust nylon NATO straps or marine elastomers are excellent choices. Selection depends on your intended usage and dial colour: pair warm tones (cognac, burgundy) with dark dials, neutral tones (grey, cream) with light dials.

Changing the Streamliner 6200-1200 strap requires a spring bar removal tool. Locate the two horizontal pins at the case extremities, gently compress the pin with the tool to release the internal spring, and remove the worn strap. Insert the new pins into the 18mm aftermarket strap and align with the case lugs, pressing until you hear a click. If inexperienced, our Casati Milano atelier offers strap-change service by appointment.

Yes, absolutely. The Streamliner 6200-1200 is compatible with any high-quality 18mm strap. We recommend choosing specialised brands that guarantee precise dimensional tolerances and durable materials. Our handcrafted 18mm straps are specifically tested on this reference and maintain the aesthetic standards of the original integrated bracelet.

A high-quality leather strap (alligator, calf, shell cordovan) typically lasts 3–5 years with daily use, depending on exposure intensity to perspiration, moisture and mechanical wear. Vegetable-tanned leather develops a natural patina that improves appearance over time. Shell cordovan straps are particularly durable (5–7 years). To extend lifespan, we recommend regular cleaning, drying after water contact and rotation with alternative straps. Technical straps (NATO, elastomer) last 2–4 years and are more economical to replace.
