The "London" clock benefits from a super durable, tarnish-free coating meaning you never need to polish it. The instrument features a good quality quartz movement and black roman numerals upon a crisp white face. Uses 1xAA battery. TARNISH-FREE - Tarnish-free instruments have been coated with a newly developed protective coating using advanced surface treatment technology. Far superior to lacquers and varnishes, it can withstand more than 720 hours (the longest test period for this process) under NSS (Neutral Sea Salt) laboratory testing. NSS testing is a certificated and standardised test method used to check corrosion resistance of coatings on metals such as brass, zinc and steel. This means your instruments will stay looking good for longer even when exposed to the harsh marine environment for extended periods.
