Frequently asked questions

What is the lug width of the Glashütte Original Sixties 1-39-52-03-02-04?

The lug width is 20 millimetres. This dimension is specific to the Sixties model and is calculated to maintain correct proportions between the case and strap. To verify compatibility, measure the space between the lug bars: it must correspond exactly to 20 mm.

What is the best strap for the Glashütte Original Sixties 1-39-52-03-02-04?

This depends on your lifestyle and usage. A quality alligator strap conveys sober luxury. Cognac-coloured calf develops a unique patina over time. For versatility, a NATO in slate grey or faded blue is excellent. If you prefer absolute durability, shell cordovan remains unbeatable. For sports contexts, anthracite grey rubber offers practicality without compromise.

How do I change the strap on my Sixties 1-39-52-03-02-04?

Remove the watch from the current strap by extracting the lug bars from their respective seats in the case. Insert the new bars into the destination strap, ensuring they enter in the correct orientation. Position the strap on the lugs and verify that everything is secure. If the strap has a deployante, check that the closing mechanism functions correctly.

Can I use an aftermarket compatible strap with the Glashütte Original Sixties 1-39-52-03-02-04?

Yes, absolutely. As long as the lug width is 20 millimetres, you can pair any quality strap: leather, NATO, rubber, alligator or shell cordovan. Always verify the seller's specifications and compatibility before purchase.

How long does a leather strap last on the Sixties 1-39-52-03-02-04?

A quality leather strap can last 5-10 years with ordinary maintenance. Longevity depends on the type of tanning (vegetable tanned leather resists time better), daily use, climate and exposure to humidity. Shell cordovan and premium alligators easily exceed 10 years. Protect the strap from excessive moisture and prolonged contact with sweat.
