FAQ

What is the lug width of the Glashütte Original Sixties 1-39-52-10-02-01?

The lug width of the Glashütte Original Sixties 1-39-52-10-02-01 is 18 millimetres. This measurement refers to the horizontal distance between the outer edges of the spring bar holes on the lugs. It is essential to verify this measurement before ordering an aftermarket strap, as an incorrectly sized passant would cause mechanical friction and instability during wear.

What is the best strap for the Glashütte Original Sixties 1-39-52-10-02-01?

The best strap depends on your intended usage. For formal elegance, we recommend dark brown or black alligator with vegetable tanning, which emphasises the aesthetic purity of the stainless steel case. For a sporty and versatile option, a slate-grey NATO strap or a black FKM rubber model maintains the austere styling. For those seeking authentic patina development over time, light-brown vegetable-tanned calf leather offers genuine aging and personalisation.

How do you change the strap on the Glashütte Original Sixties 1-39-52-10-02-01?

The Sixties uses standard prismatic spring bars that are easily removable. Position the watch on a soft surface to avoid scratches. Using a dedicated spring bar tool, gently lever one bar until it releases from its housing. Repeat on the other end. Insert the new bar into the lug holes and press until it locks into place with an audible click. Verify that the strap is secure before wearing the watch.

Is the Glashütte Original Sixties 1-39-52-10-02-01 compatible with aftermarket straps?

The Glashütte Original Sixties 1-39-52-10-02-01 is fully compatible with any strap featuring an 18-millimetre lug width. The spring bars are standard and require no modifications. Always verify that the strap's caliper (thickness) is consistent with the case geometry to avoid excessive compression or play.

What is the average lifespan of a leather strap on the Glashütte Original Sixties 1-39-52-10-02-01?

A quality leather strap, such as alligator or shell cordovan with vegetable tanning, typically lasts 4–6 years with daily wear, provided appropriate maintenance is undertaken. Longevity depends on exposure to perspiration, humidity, thermal fluctuations, and frequency of use. A thick calf leather (approximately 2.0–2.2 millimetres) offers greater durability than thin hides. A deployante clasp, if present, provides additional longevity compared to traditional passants.
