Omega Seamaster “Baby Ploprof” 166.0251 – 39mm – Japanese Market – 1979 Rare
We hear it all the time — “find me another one” — and this is exactly one of those watches.
This Omega Seamaster reference 166.0251, often nicknamed the “Baby Ploprof”, is an exceptionally rare piece, made even more desirable by being fitted to its original bracelet — something very few examples have managed to retain.
Produced specifically with the Japanese market in mind, particularly in this silver dial configuration, this is a standout vintage Omega with both rarity and character.

Our View
The “Baby Ploprof” is one of Omega’s most interesting and under‑the‑radar vintage divers. Sharing design DNA with the iconic Ploprof — particularly the hands — it offers a more wearable 39mm case while retaining the bold aesthetic.
What truly sets this example apart is the combination of Japanese market origin, silver dial, and original bracelet — a trio that is becoming increasingly difficult to find.
This is not a perfect, polished piece — and that’s exactly the point. It’s an honest, original watch with real presence and rarity. A fantastic opportunity for collectors and, in our view, one to hold for the future.
