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 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.
Solid stainless steel case with brushed steel sides, polished top and back. Unidirectional bezel with luminous numbers in the bezel insert sealed with hardened acrylic. Screw back and screw down crown; the crown assembly is identical to that employed in the "Dreadnought" and has been tested to 2000 metres. Domed acrylic crystal in keeping with the original design. The dial is soft iron anti-magnetic and the polished steel sword hands are filled with Super Luminova, as are the indices.
Each watch has its own unique serial number, which also identifies the date of manufacture, engraved on the case back.
40mm diameter across the bezel and 46.6mm to the tip of the signed crown. 47mm lug tip to lug tip and 14.3mm thick tot he top of the domed crystal. Lug spacing is 20mm and the watch head without strap weighs 90 grammes.
ETA 25 jewel automatic, calibre 2824-2 (standard). Supplied in box with 12 months guarantee and choice of Time Factors Aviator, Rally or Carbon strap. Also supplied with a spare crystal and tube of Polywatch.
