Strap for Senator Excellence Panorama Date Moonphase Red Gold / Silver / Nubuck - Pin

The lug width of the Glashütte Original Senator 1-36-24-02-05-02 is 21mm. This dimension is specific to the model and represents the optimal compromise between the 40mm case and wrist ergonomics. To measure correctly, position a calliper between the spring bar attachment points or count millimetres centre-to-centre between the mounting holes.

For the red gold Senator, the most suitable materials are alligator (Nile crocodile skin with formal rectangular grain), shell cordovan (horsehide from the rump, with a patina that ages alongside the watch) and vegetable-tanned calf (elastic with fine grain). Alligator represents the most elegant choice, whilst cordovan offers an intimate patina that develops over years of wear. Calf is the middle ground.

Changing the Senator strap is accomplished using a spring bar remover tool. Insert the tool tip into one of the lateral spring bar holes, gently push towards the case centre to release the spring from its housing. Remove the old strap and insert the spring into the new strap, ensuring it is positioned correctly and symmetrically. Repeat for the opposite side.

Yes, it is possible to fit aftermarket straps with 21mm lug width on the Senator 1-36-24-02-05-02. However, 21mm is a specific dimension and limits choice to bespoke artisanal straps. Universal straps are not compatible. Artisanal quality is recommended to preserve the original constructive excellence of the timepiece.

The lifespan of a leather strap for the Senator depends on material and daily wear. An alligator or cordovan strap can last 5-10 years with regular use and appropriate maintenance (periodic drying and conditioning). Vegetable-tanned calf has a similar lifespan, though generally shorter than cordovan. The patina that develops is evidence of natural ageing, not deterioration.
