Strap for SeaQ Date Stainless Steel / Black / Rubber - Folding

The lug width of the Glashütte Original SeaQ 1-39-11-06-60-33 is 20 mm, measured internally from lug to lug. This dimension is standard across all stainless steel SeaQ models and ensures optimal proportions on the 39.50 mm case diameter.

The choice depends on intended use: alligator is the classical solution that enhances German elegance without visual competition; vegetable-tanned leather offers predictable ageing and warm tones; tactical NATO ensures water resistance and quick changes; vulcanised rubber is ideal for those wishing to emphasise the athletic character. The 20 mm lug width is compatible with all these materials.

The SeaQ uses a standardised bayonet lug system. With a small-diameter tool (ballpoint pen or dedicated tool), insert the tip into the lateral lug hole and gently lever to unlock the mechanism. The strap will come free easily. Insert the new 20 mm strap by aligning the bayonet and push until it clicks into place. No specialised tools required for this reversible operation.

Yes, perfectly compatible. Any strap with a 20 mm lug width will fit the SeaQ 1-39-11-06-60-33 without modification. milanostraps.it offers a comprehensive collection of 20 mm straps in various finishes and materials, all tested for mechanical and aesthetic compatibility with the SeaQ.

A well-maintained vegetable-tanned calf leather strap lasts 4–6 years before requiring replacement due to natural wear. Alligator is more durable (5–8 years). In environments of frequent water or humidity exposure, we recommend NATO or rubber, which guarantee 10+ years of durability. Periodic maintenance (drying, conditioning with balm) significantly extends the life of a leather strap.
