A brief history on the Tudor Big Block.
Released in 1976, the Tudor Prince Oysterdate was first introduced and was the first automatic chronograph made by Tudor. This new Prince Oysterdate, was also known by the names Automatic Chrono Time or just Chrono Time and as they were thicker than any other Tudor model due to the automatic movement, watch collectors started calling them the Tudor Big Block . This name became synonymous with this model, so much so that the name â€śBig Blockâ€ť was used in the following 79100 series introduced in 1989.
In the “newer” models brought out in 1989, the movement was the superb and highly reliable Valjoux calibre 7750. The architecture of this new movement brought about a significantly altering the dial with the addition of an hour counter, moving the group of counters towards the left of the dial, and the relocation of the date aperture to 3 oâ€™clock.
Now more than ever, the Tudor Big Block has become one of the most collectable Tudor watches on the market today.
