More about Tudor:

The non-date Tudor 7016 and date 7021 were first introduced in 1968 and had big modifications compared to the aging Tudor reference 7928. While the non-date 7016 was a direct evolution of the last Tudor the 7021 was introduced at the same time as Rolex was releasing the Submariner date 1680. However the Tudor version has the fun roulette wheel date indicator similar to early Rolex datejusts. Finally the 7021 came in two colors, black and blue, the later has now achieved cult status among Tudor collector.

This particular example is in excellent condition with beautiful cream luminous and a gorgeous  patina bezel. The dial blue is less dark than in the photograph. A beautiful vintage daily wear for anyone.
