Ship's clock

We brought the inside of the clock home from the boat yesterday as it had stopped working and did not respond to a battery change. It has a quartz movement behind the impressive face so really cannot be called a chronometer.
I left it on the kitchen table to enjoy the glow from the Aga while I cooked the roast . When I looked at it later it was ticking away happily. We decided perhaps it was cold. Good thing we have no plans to sail the Southern Ocean .
