Frequently asked questions

What is the lug width of the IWC GST Aquatimer IW3568-07?

The lug width of the IWC GST Aquatimer IW3568-07 is 22 millimetres. This dimension is standard for this model and represents the internal distance between the two suspension pins of the strap. It is essential to verify this measurement before purchasing an aftermarket strap to ensure compatibility and attachment stability.

Which strap is recommended for the IWC GST Aquatimer IW3568-07?

For the IWC GST Aquatimer IW3568-07, straps in alligator are recommended for sophisticated elegance, shell cordovan for evolved natural patina, vegetable-tanned calf for aesthetic minimalism, and vulcanised rubber for maximum diving functionality. The choice depends on use: formal, everyday, or technical-professional.

How do I change the strap on my IWC GST Aquatimer?

To change the strap on your IWC GST Aquatimer IW3568-07, use a spring bar tool or dedicated watch tool. Position the watch case-up, locate the lateral pins, gently push the first pin outward until it exits the hole completely. Repeat for the second pin. Insert the new strap by aligning the lugs with the holes and reinserting the pins. Professional assistance is advised to prevent damage.

Can I use a quality aftermarket strap on this IWC?

Yes, any artisanal quality strap with a 22mm lug width is compatible with the IWC GST Aquatimer IW3568-07. Straps crafted in alligator, calf, shell cordovan or technical rubber represent authentic choices. It is crucial to verify that the strap is constructed to millimetre-precision standards to ensure stability and avoid damaging the original attachments.

How long does a leather strap last on this watch?

A quality leather strap for the IWC GST Aquatimer, if properly maintained, has an average lifespan of 3-5 years with daily wear. Longevity depends on tanning method (vegetable tanning resists better), climatic conditions, water exposure and leather type. Alligator and shell cordovan age elegantly and develop patina over time.
