Frequently asked questions

What is the lug width of the IWC GST Aquatimer IW3568-01?

The lug width of the IWC GST Aquatimer IW3568-01 is 22mm. This width is specifically dimensioned for the proportions of the 44mm case and is the technical specification that determines compatibility with any aftermarket strap. Measure the distance between the two lugs on either side of the case to verify that your strap is compatible.

Which strap do you recommend for the GST Aquatimer IW3568-01?

For the GST Aquatimer IW3568-01, we recommend an alligator strap in vegetable tanning, which creates aesthetic consonance with the model's marine vocation and develops a fascinating patina over time. Alternatively, high-quality calf leather offers robustness with a softer hand, while a NATO strap or vulcanised rubber strap represents the most functional choice for those intending to wear the watch in aquatic environments. The choice depends on the balance between aesthetics and actual usage.

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

To change the strap on the GST Aquatimer IW3568-01, you must remove the two spring bars (one on each side of the case) that hold the strap in position. Use an appropriate tool (spring bar tool or dedicated instrument) to extract the bars by gently pushing towards the centre and withdrawing them. Once the bars are removed, the old strap lifts away easily. To fit the new strap, position it on the case, insert the bars into their respective lugs ensuring the lug width is exactly 22mm, and push the bars until they click into position.

Is an aftermarket strap compatible with the GST Aquatimer IW3568-01?

Yes, any strap with a 22mm lug width is compatible with the GST Aquatimer IW3568-01. Always verify this measurement before purchase. Artisanal straps in leather, fabric or rubber offer superior customisation opportunities compared to factory straps, allowing you to adapt the aesthetic character of the watch to your personal style while maintaining maximum technical compatibility.

How long does a leather strap last on the GST Aquatimer IW3568-01?

The lifespan of a leather strap depends on usage and maintenance. A high-quality alligator or calf strap, made with vegetable tanning, typically lasts between 3 and 5 years under moderate daily wear conditions. If the watch is frequently worn in aquatic environments or exposed to prolonged humidity, durability may reduce to 1-2 years. Periodic maintenance—avoiding direct water exposure, allowing rapid drying in case of water contact, occasionally applying conservative treatments—significantly extends the strap's lifespan.
