Hello Watchex, Ref. 168.005 — The Tritium Transition. This is the Omega Constellation for the detail-obsessed collector. The “Single T” beneath “Swiss Made” marks a short-lived transitional period when Omega began phasing out radium in favor of tritium — making this dial layout extremely scarce. Classic pie-pan dial with applied markers, dagger hands. Add the hidden-lug case and you’re looking at one of the most iconic mid-century chronometers ever made — with a subtle historical twist. 📏 34.5mm diameter 📏 10mm thickness 📏 42mm lug-to-lug 📏 Wrist shown: 17cm (6.7 inches) Timestamp: https://drive.google.com/file/d/1MjLkTGK1TXJDnCE2GMWn-qZgEteuraQk/view?usp=drivesdk Pricing, Payment & Shipping 💵 Price: $1630 + shipping (coms with all original parts and working condition goes for up to $2000) 📦 Shipping: $40 (UPS Express 3-5 days with tariffs taken care by me!) 💲 Payment: PayPal F&F or G&S (buyers add 4.6%) 🚫 No trades at this time For more vintage pieces, check out my Instagram: vintagewatch.lab Thanks for looking!
