Strap for Senator Excellence Panorama Date Moonphase Stainless Steel / Silver / Synthetic

The lug width is 21mm, corresponding to the distance between the two spring bar pins integrated into the case. To verify compatibility of a strap, measure the exact distance between the case lugs with a digital caliper: it must match 21mm precisely. Incorrect measurement is the most common cause of incompatibility.

An alligator strap in polished or matte finish is the most authentically Saxon choice: the regular texture pairs naturally with the stainless steel and the constructive philosophy of the movement. For those prioritising breathability and evolution over time, vegetable-tanned calfskin develops a rich patina. NATO is ideal for daily wear, whilst natural rubber is recommended for aquatic contexts.

Remove the spring bar from the case lugs using an appropriate tool (spring bar tool). Extract the obsolete strap and insert the pins of the new strap into the vacant spaces, then reinsert the spring bar ensuring it is firmly locked. Verify that the strap is positioned symmetrically with respect to the case before wearing the watch.

Yes, provided the lug width is 21mm. Any strap compatible with this measurement—alligator, calfskin, shell cordovan, NATO, rubber—can be used on the Glashütte Original Senator 1-36-04-01-02-64. We recommend verifying the build quality and finish of the lugs to prevent scratches on the case.

Durability depends on use intensity and leather quality. A high-quality alligator strap with vegetable tanning lasts an average of 3–5 years of daily wear, developing a noble patina attesting to its use. Calfskin straps with vegetable tanning have similar durability. Leather tends to become brittle at the creases after 4–6 years of direct contact with perspiration and skin moisture.
