The Glashütte Original Senator Excellence Panorama Date Moonphase (ref. 1-36-24-05-02-61) features the caliber 36-24 movement visible through a platinum caseback. The 40mm stainless steel case houses a guillochéed dial with large date and moonphase complications.

Frequently asked questions

What is the exact lug width of the Glashütte Original Senator 1-36-24-05-02-61?

The lug width of the Glashütte Original Senator 1-36-24-05-02-61 is precisely 21.00mm, measured in the internal space between the lugs on the case. This specific width requires dedicated 21mm straps and is not compatible with 20mm or 22mm standards. Measure correctly by placing a digital calliper between the lugs without including case curvature.

What strap material is recommended for the Glashütte Original Senator 40?

For the Senator, Mississippi alligator is ideal to complement the guillochéed dial, vegetable-tanned calf offers natural patina over 12-18 months, dense-weave NATO recallares the vintage 1970s aesthetic, and FKM rubber in textured finish suits daily non-formal wear. Selection depends on usage context and desired ageing profile.

How should you correctly change the strap on the Senator 1-36-24-05-02-61?

Strap changing requires a spring bar tool matched to refined lugs. Position the watch horizontally on soft cloth, press the spring bar internally to free the pin, remove the old strap, and insert the new one until the spring bar clicks into position. Verify the strap sits flush between the lugs with no metal exposure.

Are aftermarket straps compatible with the Glashütte Original Senator?

Any 21mm strap conforming to ISO 1996-2 standards is compatible with the Senator 1-36-24-05-02-61, regardless of manufacturer. Artisanal straps from milanostraps.it in alligator, vegetable-tanned calf, NATO and FKM rubber are tested for Glashütte lugs and offer certified construction quality.

How long does a leather strap last on the Glashütte Original Senator?

A quality leather strap on a daily-worn Senator typically lasts 3-5 years before requiring resurfacing. Vegetable-tanned alligator develops rich patina after 12-18 months. Natural ageing is considered a virtue, whilst woven NATO resists 5-7 years with minimal wear. FKM rubber maintains structural integrity for 4-6 years in continuous use.
