Frequently asked questions

What is the lug width of the Glashütte Original SeaQ 1-39-11-06-60-05?

The lug width is 20 mm. This dimension is specific to the SeaQ model and refers to the free space between the spring bars when fully extracted. Selecting a strap with this exact width is essential to prevent slippage or mechanical stress on the case.

Which strap is best suited for the SeaQ 1-39-11-06-60-05?

For the SeaQ, we recommend alligator or shell cordovan, given the sportive-elegant aesthetic of the stainless steel case. Black or dark brown alligator amplifies contrast with the blue dial; cordovan develops rich patina over time. For intensive use, NATO canvas or FKM rubber ensures practicality and durability without aesthetic compromise.

How do I change the strap on the Glashütte Original SeaQ?

Use a spring bar tool to gently press the small mechanisms on either side of the lug. Once released, the bars retract and the original strap slides away. Insert the bars of the new 20 mm strap into the lateral housings until they click. Verify the strap is securely fastened before wearing the watch.

Can I use an aftermarket strap on the SeaQ 1-39-11-06-60-05?

Absolutely. Any 20 mm quality strap is compatible with the SeaQ. We recommend artisanal straps from Casati Milano, crafted with noble materials: they guarantee constructive precision, attention to detail, and longevity. Avoid budget straps with imprecise millimetre tolerances.

How long does a natural leather strap last on the SeaQ?

An alligator or shell cordovan strap with vegetable tanning lasts 3–5 years with regular maintenance. Durability depends on frequency of use, climate conditions, and care. Store the strap away from excessive humidity and prolonged direct sunlight. Apply protective balm every 6–12 months to maintain flexibility and prevent cracking.
