For sale Omega Speedmaster Professional 3572.50 with tritium dial and display back. During a very short period, a transitional 3572.50 was produced with the new 1863 caliber and the tritium dial/hands. Many collectors consider it as the best of the two worlds: the more discrete rhodium-plated movement and the yellowish paint of the dial indexes. Tritium markers and hands have aged to beautiful cream shade. Watch comes in Omega box only. Price: €6000. Watch is located in Riga, Latvia, insured international shipping at cost.
