Antique Chatham Nautical Barometer - Brass - 180mm Ref18: NC-6767
This unique QuickFix system allows the instrument to be locked hard to a bulkhead or wall but removed, in seconds, by hand. The instrument is supplied with a case plate which is screwed to the wall or bulkhead (instructions and drill hole template included). The instrument then simply slots over the base plate and with a gentle twist, is locked on.
A reverse twist removes it again. This makes changing batteries easy, removal for storage easy, and avoids the tricky job of not scratching your polished case when screwing the instrument to the wall! QuickFix can also act to seal the instrument mechanism making it waterproof.
In underwater tests, clocks fitted with the QuickFix waterproof system worked continuously at a depth of 300mm for more than 3 months. Our "Chatham" range have brass cases with the ingenious QuickFix fitting system and super durable, tarnish-free coating.
Case diameter 180mm, depth 40mm. Quartz clock movements use one AA battery.
