Frequently asked questions

What is the lug width of the IWC GST Aquatimer IW3568-05?

The lug width of the GST Aquatimer IW3568-05 is exactly 22 millimetres. This construction parameter is specific to the model and determines compatibility with replacement straps. To measure the lugs correctly, verify the internal distance between the two lateral lug bars: for the IW3568-05, the value must be 22mm to ensure correct fit and maintain the case's visual proportions.

Which leather strap is best for the IWC GST Aquatimer IW3568-05?

Nile crocodile leather represents the most harmonious choice for the GST Aquatimer: the natural grain texture and leather density create balanced contrast with the brushed steel case surface. Dark brown crocodile (mahogany tone) is recommended for black dials; medium cognac for blue variants. Alternatively, shell cordovan offers superior structural rigidity with a patina that evolves elegantly over time.

How do you change the strap on an IWC GST Aquatimer?

The GST Aquatimer IW3568-05 strap is replaced by first removing the safety crown to avoid case stress. Using a spring bar tool, insert the tip into the lateral case recess and gently lift one of the spring bars. Then extract the old strap and insert the new one, aligning the bars correctly. Repeat on the second side, verifying that the strap is symmetrical and properly seated.

Is an aftermarket strap compatible with the IWC GST Aquatimer IW3568-05?

Yes, any strap with a 22mm lug width is compatible with the GST Aquatimer IW3568-05, regardless of brand. The 22mm width is the determining construction parameter. Artisanal customizable straps on milanostraps.it guarantee complete compatibility and permit choice of leather, initials, and stitching thread colour.

What is the lifespan of a leather strap on a dive watch like this?

A high-quality natural leather strap has an average lifespan of 5-7 years with intensive use and regular water exposure. Frequent exposure to moisture, salt water, and UV rays accelerate fibre degradation. For the GST Aquatimer, we recommend alternating the leather strap with FKM rubber or NATO options during diving activities. Vegetable-tanned leather straps develop more resilient patina over time compared to chrome-tanned alternatives.
