For sale is my IWC Mark XII, one of the most balanced and wearable pilot watches ever produced. This example stands out for its beautifully aged tritium patina and its exceptional originality — original dial, original hands, original bracelet, and the correct fish-logo crown. This is a watch for collectors who value condition, correctness, and subtlety. The watch was recently in with my watchmaker for a light regulation and to repair the quickset day function, which was previously inconsistent. The issue has been fully resolved — the day and date now set properly, and the watch is running strong and accurately. The watch also comes with an eBay Authenticity Guarantee card, having previously passed independent third-party authentication. While I’m selling privately now, this provides an added layer of confidence regarding originality and condition. I’m only selling because it competes directly with my Explorer I for wrist time. I genuinely love this watch and would be happy keeping it — it will only leave if it finds the right next owner. ⸻ Details • Model: IWC Mark XII • Case size: 36mm • Movement: IWC Cal. 884/2 (JLC-based) • Dial: Original tritium with even, warm patina • Hands: Original tritium • Crown: Original fish-logo crown • Bracelet: Original IWC bracelet (extra links included) ⸻ Condition • Excellent overall condition with honest wear • No replacement parts • Patina is uniform and highly attractive • Crystal is clean • Day/date functions correctly after recent service work ⸻ Recent Work • Light regulation • Quickset day repair (now functioning properly) ⸻ Why the Mark XII The Mark XII sits at a rare intersection of: • Vintage proportions • Modern reliability • JLC-derived movement • Understated, timeless design It wears effortlessly, disappears on the wrist, and rewards long-term ownership. ⸻ Price & Terms • $4,975 • PayPay FF or Venmo preferred • Fully insured shipping included • No trades — consolidating collection • References available This is a top-tier Mark XII with documentation and recent work.
