Strap for Senator Panorama Date Moon Phase Stainless Steel / Silver / Bracelet

The Senator 100-04-32-12-14 features a standard lug width of 20 millimetres. This measurement is proportionate to the 40mm case and is compatible with all straps in our 20mm collection. To verify correct lug width, position the calliper perpendicular to the watch's wrist location at the widest point of attachment.

We recommend straps in vegetable-tanned alligator or shell cordovan: the grain of the leather dialogues perfectly with the Glashütte decorations visible through the transparent case back. Chocolate brown or black alligator enhances the sophistication of the steel case. For daily wear, finished calf leather with regular texture offers elegance with practicality. Technical vulcanised rubber straps are ideal for those seeking versatility without compromise.

Strap changing requires a specific tool (spring bar removal tool) and care. Position the watch on a soft cloth, locate the pins connecting the lug to the case, push the tool from the inner side outwards to extract the pin. Once the lug is free, insert the new strap following the reverse procedure. If you're inexperienced, Casati Milano offers strap-changing service by appointment.

Yes, provided the strap has a lug width of 20 millimetres. All straps in our 20mm collection are fully compatible with the Senator. We recommend always verifying lug width before purchase: incorrect width compromises the aesthetics of the original design.

Durability depends on material and usage. Vegetable-tanned alligator lasts approximately 5-7 years with daily wear, developing a desirable patina. Shell cordovan, more resistant, can last 10+ years. Vulcanised rubber lasts 3-5 years before losing elasticity. Regular maintenance—avoiding prolonged exposure to moisture and heat—significantly extends strap life.
