Footnotes:
These were the first chronographs produced by Tudor and are instantly recognisable by the distinctive dial with angled blue subsidiary dials instead of the more normal circular subsidiaries used by the other chronographs of its time. The combination of the vibrant orange chronograph seconds hand and 5 minute markers against the blue grey dial is a great example of 70's design and a look that remains distinctive working equally well today as it did when it was produced.
