The Anchor range of porthole instruments sit recessed into mahogany-coloured wooden boards and plinths. They feature cream faces with black hands and roman numerals, and 10cm cases which have been treated with a special tarnish free coating so that they do not require polishing. Quartz clock movements use 1x LR1 battery (not supplied). Barometers display pressure in millibars and inches. This set comprises a clock and barometer mounted in a traditionally-shaped board measuring 26x13cm.
