Glashütte Original
Senator 1-36-03-03-02-31— lug 20mm

The Glashütte Original Senator 1-36-03-03-02-31 is equipped with a lug width of 20 mm. This measurement is specific to the model and determines the compatibility of replacement straps. To verify it correctly, use a digital calliper positioned perpendicularly between the inner walls of the two lugs: the result must be exactly 20 mm. It is essential to measure with precision before ordering a strap, as even differences of 2 mm (18 mm or 22 mm) will render the strap incompatible.

The choice of the best strap depends on the intended use and personal aesthetic preferences. For formal contexts, a dark brown or black alligator strap enhances the elegant nature of the Senator. If you prefer natural patina development over time, vegetable-tanned calf in caramel-brown offers chromatic depth and organic character. For daily versatility, a shell cordovan strap in burgundy creates a balance between formality and dynamism. If you desire a sporty approach without aesthetic compromise, a NATO strap in vegetable-tanned textile in grey or sand is highly appropriate. FKM rubber remains the most durable solution for humid environments.

To change the strap, follow these steps: (1) position the watch on a soft surface (microfibre cloth) with the dial facing downward; (2) locate the spring bar—the small metallic pin that connects the strap and lugs; (3) use a spring bar tool (specific implement with two concave ends) to gently compress the spring bar towards the watch centre; (4) remove the old strap; (5) insert the new strap by aligning the lug with the spring bar and release it. The operation requires delicacy to avoid scratches on the case. If inexperienced, consult a professional watchmaker or the Casati Milano atelier for professional strap changing.

Yes, any strap with a 20 mm lug width is physically compatible with the 1-36-03-03-02-31. However, aesthetic and functional compatibility requires attention: verify that the lug thickness is adequate (generally 4.5-5 mm for the Senator), that the total length allows comfortable wrist closure, and that the chosen materials reflect the Saxonian spirit of the watch. The artisan straps from milanostraps.it are specifically dimensioned and finished to enhance the Senator's original proportions, guaranteeing complete dimensional and aesthetic compatibility.

The durability of a leather strap depends on the material, use, and maintenance. An alligator strap with vegetable tanning, if worn daily and with proper care, lasts 4-6 years before requiring replacement. A shell cordovan strap, thanks to superior leather density, can last 6-8 years. Standard calf lasts 2-4 years in intensive use. To extend useful life: avoid prolonged water immersion, do not expose the strap to direct heat sources, and occasionally apply a leather-specific conditioner (natural creams without solvents). Natural wear and patina are desired—they represent the noble ageing that characterises high-quality artisan straps.
