Strap for Senator Cosmopolite White Gold / Rainbow / Alligator / Folding

The lug width of the Glashütte Original Senator 1-89-02-01-40-50 is 21 millimetres. This measurement corresponds to the proportions of the 44mm case and should be verified using a digital calliper positioned perpendicularly between the internal attachment points of the lugs.

For the Senator 1-89-02-01-40-50, straps in premium alligator (black or burgundy), Tuscan vegetable-tanned calf, or Japanese shell cordovan are recommended. These materials maintain the aesthetic equilibrium of the white gold and the formal nature of the model. Straps must have a 21mm lug width for compatibility.

Strap replacement is performed using a dedicated spring bar tool to compress the fastening springs at the lugs. The operation should be executed on a soft, stable surface with adequate lighting. For luxury timepieces such as the Senator, professional assistance is advisable to ensure maximum precision and safety of the operation.

Yes, it is possible to use quality aftermarket straps, provided they are manufactured for the 21mm lug width. Milano Straps offers a selection of leather, rubber and textile straps specifically dimensioned for this width, guaranteeing structural and aesthetic compatibility with the Senator 1-89-02-01-40-50.

The durability of a leather strap depends on frequency of use and material quality. A premium alligator or shell cordovan strap can last 5-7 years with moderate daily wear. Vegetable-tanned leather tends to develop patina over time, improving aesthetic appeal. Regular maintenance (gentle cleaning, avoiding excessive moisture) extends the useful life of the strap.
