Precista was a brand which was owned by UK watch wholesaler Southerns (there had been previous owners). It would seem that Precista military timepieces were supplied for a relatively limited period of time, perhaps as short as 18-20 years. Certainly, W10 and 6BB (RAF) general service watches were issued in 1982 onwards and diver watches in the late 1980s through to 1993 utilising different case styles. Previously to this was the asymmetric case manual wind chronograph bearing the Precista name and this would date to the early to mid 1970s. By the end of the 1990s, Southerns had ceased trading and the Precista brand slipped into disuse. Thus Precista ceased to be, leaving a military pedigree; original Precista issued watches are now sought after due to their relative scarcity.
