Frequently asked questions

What is the lug width of the Swatch Scuba Fifty Fathoms SO35G100?

The lug width of the SO35G100 is 22 mm. This measurement represents the internal distance between the two lug attachments on the watch case. To verify correctly, place a ruler between the horizontal metal pins protruding from the case, measuring only the internal distance (from inner shoulder to inner shoulder).

Which strap is best suited for the Swatch Scuba Fifty Fathoms?

Selection depends on intended use. For lasting elegance, vegetable-tanned leather (calf, deer, alligator) is recommended, developing patina over time. For sporting versatility, a technical NATO strap offers practicality and breathability. For frequent diving, a vulcanised rubber strap with grip pattern ensures secure grip in wet conditions. All are available in 22 mm at milanostraps.it.

How do I change the strap on the Swatch Scuba Fifty Fathoms SO35G100?

Remove the watch from your wrist. Using a spring bar tool or sterilised needle, press the horizontal lug pins, disengaging them one at a time from the case holes. Once one end is released, fully extract the spring bar. Insert the new strap by aligning the lug pins with the holes, pressing until a secure click is felt. The procedure typically takes approximately 3 minutes with practice.

Are aftermarket straps compatible with the SO35G100?

Yes, provided they are 22 mm lug width. The handcrafted straps from milanostraps.it are specifically manufactured in this dimension for your model. Always verify compatibility by ensuring lug pins enter case holes without forcing. Quality aftermarket straps offer refined finishing at the extremities (pass-throughs and lugs) that respect the SO35G100's proportions.

How long does a leather strap last on this watch?

Durability depends on construction quality and usage frequency. A vegetable-tanned leather strap with well-defined pass-throughs typically lasts 3 to 5 years of daily wear, developing appreciable patina. Frequent water exposure (showers, pools) reduces lifespan; regular diving favours technical rubber instead. Regular maintenance (cleaning, drying, monthly oil treatment) significantly extends leather strap longevity.
