The Precista 300 follows the tradition of paying homage to military and military-style wristwatches of the past, in this case it follows and improves on the specification of British Ministry of Defence Standard 66-4, Part 1 Issue 2. This revision is dated 1 January 1971.
This is arguably the most popular military dive __watch today and good examples are keenly sought and command a high price.
This edition bearing the Precista name has been faithfully manufactured to the original specification, improving on it where appropriate. The most significant improvement is the addition of an anti-magnetic movement cover, movement holder and soft iron dial giving the __watch anti-magnetic resistance to 80,000 A/m (Amp metres), the same as modern day IWC and Sinn watches. This has increased the thickness of the watch by 3mm over the original.
