The Pirates IDPTWASS, seen from the bench

The Montegrappa Pirates IDPTWASS is a 43mm stainless steel watch combining bold aesthetics with Swiss craftsmanship. Powered by the ETA 2824-2 automatic movement with date window at 3 o'clock, it features a mixed-finish case with satin and polished surfaces and sapphire caseback. The 22mm lug width was selected to maintain proportions between the case and wrist, with curved lugs requiring correspondingly curved straps for proper fit.

Frequently asked questions

What is the lug width of the Montegrappa Pirates IDPTWASS?

The lug width of the Montegrappa Pirates IDPTWASS is 22mm. This dimension was selected by designers to maintain balanced proportions between the 43mm case mass and wrist fit. Always verify the internal measurement between lugs using a calliper, as the lug curve can influence perceived fit.

Which strap is recommended for the Montegrappa Pirates IDPTWASS?

For the IDPTWASS we prioritise high-quality alligator in dark shades (cognac brown, black), or vegetable-tanned calf with pronounced grain. For a versatile sporty option, a satin-finish NATO in slate grey complements the steel case excellently. FKM rubber is ideal for aquatic environments.

How do I change the strap on my Montegrappa Pirates IDPTWASS?

The process is straightforward: use a spring bar tool or small flat screwdriver. Position the watch with the case facing downward, and gently extract the lug pins by pushing from one side. This requires care to avoid scratching the case. Insert the new strap by aligning the holes to the same depth and reposition the pins. If inexperienced, consult a professional watchmaker.

Can I use an aftermarket compatible strap with the IDPTWASS?

Absolutely. Montegrappa uses standard 22mm lugs, so any quality strap with 22mm lug width will be compatible. However, verify that the strap's curve radius respects the curved lug architecture of the Pirates. Milano Straps provides a selection of 22mm straps specifically curated for this model.

How long does a leather strap last on the Montegrappa Pirates IDPTWASS?

Longevity depends on material and usage. High-quality vegetable-tanned alligator resists 5-8 years with regular use and proper maintenance (periodic cleaning, protection from excessive moisture). Classic calf lasts 3-5 years. Satin-finish NATO textile offers superior longevity, 7-10 years. Lug break or buckle wear are typically the first signs requiring replacement.
