Strap for Sixties Chronograph Stainless Steel / Silver / Alligator / Pin

The lug width of the Glashütte Original Sixties 1-39-34-03-22-04 is 20 mm. This is the standard dimension for this model, corresponding to the distance between the two spring bars protruding from the case at the extremities. To verify compatibility, measure the distance from the centre of one pin to the centre of the other, perpendicular to the case axis.

For the Sixties 1-39-34-03-22-04, alligator leather straps (for uncompromised elegance), vegetable-tanned calf leather (for developing patina over time), premium canvas NATO straps (for versatility), or FKM rubber (for aquatic environments) are recommended. Your choice depends on intended use and aesthetic preferences: alligator is the most refined, vegetable-tanned calf offers artisanal character, NATO guarantees practicality, and rubber ensures water resistance.

To change the strap on your 1-39-34-03-22-04, use a spring bar tool (specialist tool available at watch retailers). Insert the tool's tip into the lateral spaces of the case beneath the pins and gently press to compress the internal spring. The pin will release from the case hole. Repeat on the other side. Once both pins are extracted, remove the old strap and insert the new one, reinserting the pins into their slots. Work carefully to avoid scratching the case.

Yes, any strap with a 20 mm lug width is compatible. Many collectors prefer artisanal aftermarket straps because they offer superior construction quality, customisation options (colour, thickness, buckle or deployant type), and better adaptability to the wearer's wrist compared to OEM straps. Always verify that the strap features correct spring bars for the Glashütte case (pin diameter: approximately 1.5 mm).

Leather strap longevity depends on material quality, frequency of use, and environmental conditions. A high-quality alligator or vegetable-tanned calf strap, worn regularly (5–6 days per week), typically lasts 3–4 years before replacement due to natural fibre wear. If exposed to perspiration, constant moisture, or intense UV rays, durability decreases. Regular maintenance (gentle cleaning, drying, periodic conditioning with appropriate creams) significantly extends strap life.
