Frequently asked questions

What is the exact lug width of the IWC GST Aquatimer IW3568-11?

The lug width of the IW3568-11 is 22 millimetres. This measurement is consistent across all variants of the model and provides access to an extensive catalogue of artisanal and industrial straps. To verify compatibility, measure the internal space between the lug bars at 12 and 6 o'clock positions with a digital calliper: the value must correspond precisely to 22mm.

Which strap pairs best with the IWC GST Aquatimer IW3568-11?

The ideal strap depends on intended use and dial variant. For blue dials, we recommend Tuscan leather in smoked brown (testa di moro) with vegetable tanning: it creates harmonious dialogue without nautical cliché. For black dials, black alligator with brownish undertones maintains visual coherence, whilst cognac-coloured calf generates sophisticated contrast. For daily versatility, vulcanised rubber in black offers durability in wet and marine environments without compromise.

How do you change the strap on the IWC GST Aquatimer IW3568-11?

The procedure requires a spring bar tool. Grip the watch gently with the dial facing downwards, then insert the spring bar tool into the lateral groove of the lower lug. Press toward centre to compress the pin, then extract the strap from the slot. Repeat at the upper lug. Insert the new strap by aligning the bases with the lugs and actuating the pin until the security click engages. The operation takes approximately 2 minutes.

Are aftermarket straps compatible with the IWC GST Aquatimer IW3568-11?

Yes, the IW3568-11 is fully compatible with any certified aftermarket strap measuring 22mm at the lug width. On milanostraps.it you will find a dedicated selection of 22mm straps: calf, alligator, rubber, NATO and woven solutions are all available and validated for this model. Casati Milano's artisanal guarantee additionally covers personalisation including initials, custom lengths and leather selection.

How long does a natural leather strap last on the IWC GST Aquatimer IW3568-11?

Leather strap durability depends on tanning method and usage patterns. Vegetable-tanned leathers (such as Tuscan) resist degradation for 3–5 years with ordinary maintenance and moderate wear, developing appealing patina over time. Natural alligator lasts 5–7 years if protected from excessive humidity. Vulcanised rubber exceeds 10 years even in extreme marine conditions. To extend lifespan, avoid prolonged direct sunlight and salt water exposure, and occasionally apply protective balm to natural leathers.
