The SBS diver is possibly the quintessential CWC watch; whilst most other CWC watches and clocks have antecedents in other models, or have been made or supplied by other brands, only CWC has ever produced the black day-date dive watch for the British military. For this reason, as well as for the link to British Special Forces, issued versions of this watch are highly sought-after by collectors.
.
The watch was originally designed to the specifications of the Special Boat Service (SBS) in 1987; it has been suggested that special forces operatives wanted a non-reflective black metal finish for night time operations - possibly inspired by Royal Marines based in Hong Kong who had their issued RN dive watches black-coated locally - and that the day-date function was because they spent considerable amounts of time on mission and found it helpful to keep track of the days. The NSN 7995443 is specific to this watch.
.
The watch was first issued in 1988 with an acrylic bezel insert, similar to the Royal Navy dive watches of the 1980s. It was next issued in 1992 with a metal bezel insert with wide hash marks (unique to the SBS and RN dive watches of that year), and then in following years with the standard, current metal bezel insert with narrow hash marks.
Known issue years and approximate batch sizes are as follows:
1988 - service code 0552 - approximately 100 watches issued
1992 - service code 0552 - approximately 150 watches issued
1993 - service code 0555 - approximately 100 watches issued
1994 - service code 0555 - approximately 300 watches issued
1997 - service code 0555 - approximately 200 watches issued
1999 - service code 0555 - approximately 100 watches issued
2000 - service code 0555 - approximately 50 watches issued
2001 - service code 0555 - approximately 500 watches issued
2005 - service code W10 - approximately 250 watches issued

Today's example dates to 1993/1994, we know this due to the style of the Bezel. Unfortunately the issue year and number (whatever they were) has been milled out at some stage in the Watches life.
As you can see above, these SBS Watches are incredibly rare with very small quantities produced. This is estimated to be 1 of 400 produced over the years 1993/1994.
We have shown this to various CWC experts, including the author of the CWC Addict website and they are both happy that this was most likely a piece from 1993/1994.

The author of the CWC Addict Website tells me that there is also a fair chance that this Watch could have been a rarer "SP" Watch, no one knows what "SP" meant and is another interesting read over at CWC Addict, you can read that: here
