Okay, we admit it: you need to be both stickin’ rich and obsessed with maritime gadgets to want this Chelsea deck clock, given that it runs $1,750. But it’s pretty cool. Why? Well, the Chelsea Clock Company is a supplier to the US Navy and have been for over a hundred years, thanks to the navy’s need for a hyper-accurate chronometer. You likely won’t need anything that accurate (how often do you need to calculate your longitude?), but for the collector, this is the first time this clock has been made available to the public.
