At the end of each month, the hand spring is no longer under tension and allows the date hand to jump back. The IWC-manufactured 51900 caliber powering this timepiece has been elaborately finished and can be viewed through the transparent sapphire glass back. #IWCportugieser | #IWCwatches ℹ Gray dial Platinum case 44.2mm IWC-manufactured 51900 Calibre Tourbillon Mystère
