Vintage Omega Constellation Tank Silver Hobnail 155.0014 - 31mm - 1973

This 1973 Omega Constellation features a tank case design and a beautifully silver textured dial with a hobnail motif, remaining in impeccable, untouched condition. The steel case has its original polish still visible, highlighting the watch’s original and vintage character.

Inside, it houses a freshly serviced caliber 711 automatic movement, the thinner evolution of the 500-series calibers, giving the watch a refined, slim profile. The movement was serviced in October 2025 and currently runs and functions perfectly.

We’ve paired this piece with a dark brown calf leather strap (grade 3 grain) featuring a crocodile motif and a light glossy finish.

Overall, this watch is in great condition and makes for a superb dress piece or a worthy addition to any vintage Omega collection.
