Sterile 6BB–The ‘Lost’ Navigator
From Chronopedia
The 1976 MOD issued Sterile 6BB watch is somewhat of a mystery to collectors of modern British military watches. It’s cousins, the Hamilton and CWC tonneau-shaped W10 General Service watches are well-known and easily identified. See here for more information on these models:
Features
- Case is W10 tonneau shaped of monobloc construction
- Movement is only accessible from the front through the crystal
- The size is similar to Hamilton and CWC W10’s (but not exactly)
- It was only issued in 1976
- Approximately 2,000 were issued
- The dial and case are sterile e.g no manufacturer’s name or logo is applied
- Dial design is almost identical to DEF STAN 66-4(Part 5) Issue 2, Figure 1, Page 8
- The inside of the case bears no markings
- 6BB prefix would indicate it was to be issued to the Royal Air Force
