Omega Speedmaster Mark 40
The Speedmaster Mark 40, reference 3520.50, occupies an interesting position within the Speedmaster lineage. Produced through the 1990s, it moved the Speedmaster into automatic chronograph territory using the caliber 1151 - a movement based on the ETA 7751 that added day, date, and month complications alongside the chronograph function. At 39mm, the Mark 40 wears comfortably by modern standards while retaining a purposeful, tool-watch presence on the wrist.
This 1995 example comes as a full set with its original Omega red box, outer box, international warranty card, hang tag, warranty card holder, operating instructions booklet, and additional bracelet links. The black triple-register dial is clean with sharp printing and well-defined sub-dials. The luminous plots and handset appear to be original to the watch, with consistent aging throughout.
The case shows minor signs of wear consistent with regular use. Professional polishing can be arranged free of charge upon request. The bezel insert remains in good order with legible markings and no significant damage. The crystal is clean with no notable marks. The watch is presented on its original Omega stainless steel bracelet with additional spare links included, offering a comfortable and secure fit.
