IWC Portofino Automatic 356502

The IWC Portofino Automatic 356502 is a Swiss-made dress watch for men who want a classic 40 mm stainless steel case on a black crocodile leather strap. A black dial with silver-tone hands and Roman numerals at 6 and 12 o'clock gives a formal look suitable for business or evening wear.

Suits formal and business settings

This watch suits buyers who need a thin 9.5 mm profile that slips under a shirt cuff and a 30 metre water rating for daily splashes only. It is not for divers, athletes or anyone who requires a screw-down crown, chronograph functions or a bracelet option.

Easy strap change with tang clasp

The 20 mm lug width and supplied tang clasp make strap swaps straightforward using a spring-bar tool. The solid case back prevents movement visibility and the pull-push crown sets the date at 3 o'clock without a quick-set shortcut, so advancing the calendar by many days takes patience.

Questions about this item

Does the watch need a battery or manual winding to start running?

The automatic movement winds itself through wrist motion and holds a 42-hour power reserve; if it has not been worn for longer, rotate the crown a few turns before setting the time.

Will the 20 mm lug width accept the leather straps I already own?

Yes, the case uses a standard 20 mm band width, so any 20 mm strap with spring bars will fit the lugs.

How can I confirm the movement is keeping time within normal limits after setting it?

Wear the watch for a full day and compare the displayed time against a reference clock; a daily deviation of a few seconds is typical for a mechanical automatic calibre.
