FAQ
What is the lug width of the Glashütte Original Karree 39-31-06-04-0?
The lug width of the Glashütte Original Karree 39-31-06-04-0 is 18mm. This measurement is determined by the distance between the spring bars that attach the strap to the case lugs. It is essential to measure it correctly, excluding any protective end links, to ensure complete compatibility with aftermarket straps.
Which strap is best suited to the Glashütte Original Karree 39-31-06-04-0?
For the Karree 39-31-06-04-0, natural or dyed alligator is the noblest choice: its smooth grain amplifies the case's geometric purity. Vegetable-tanned calf develops a patina that evolves over time. NATO fabric straps maintain aesthetic balance in informal contexts, whilst FKM rubber is ideal for humid environments without compromising formal elegance.
How do you change the strap on the Glashütte Original Karree 39-31-06-04-0?
To change the 18mm strap, remove the spring bars using a dedicated tool (spring bar tool). Position the lever under the pin, apply gentle pressure to compress the internal spring, and extract the pin from the case lug. Insert the new strap by aligning the ends with the lugs, then push the pin until fully seated. It is advisable to perform this operation on a soft surface to prevent case damage.
Is an 18mm aftermarket strap fully compatible with the Glashütte Original Karree 39-31-06-04-0?
Yes, any strap with an 18mm lug width is compatible with the Karree 39-31-06-04-0. However, to maintain the proportional harmony of the original design, it is advisable to choose straps that respect the thickness and refinement of the case geometry. Milano Straps offers a curated selection of 18mm straps specifically chosen to ensure aesthetic balance with the German dress watch.
How long does a leather strap last on the Glashütte Original Karree 39-31-06-04-0?
The lifespan of a leather strap depends on the quality of the tanning, intensity of use, and environmental conditions. An alligator or calf of excellent quality typically lasts 5-7 years with daily wear, developing a patina that enhances its appeal. Prolonged exposure to sunlight, moisture, and perspiration shortens longevity. Vegetable tanning, rich in natural tannins, generally offers greater durability than industrial tanneries. Periodic maintenance (cleaning with a damp cloth, annual conditioning) significantly extends the strap's lifespan.
