The Mk1 was introduced in 1976 and it is acceptable to see these dials in watches with serial numbers from around 5.5 million to early 6.0 million. The Maxis ran until around 1984 with the Mk5. All the iterations of the Maxi dials have one thing in common, aside from the large hour plots; a coronet that is elegant, elongated and tall – fanning upwards from a narrow base to a wide-open top.
