The IWC Big Pilot's Watch IW5036-07 made its debut in 2021. This timepiece boasts a [CASE_DIAMETER]mm case made of [CASE_MATERIAL]. A unique feature of this limited edition (only 100 pieces available!) is the tinted sapphire crystal dial, giving a glimpse of the intricate caliber 52615 self-winding movement with a perpetual calendar. It's like having a skeleton watch without sacrificing the traditional look.
