I'm moving and looking to downsize my collection. Up for sale is an early 1960’s Titus Calypsomatic reference 5913. I am asking $2,300. This watch has become very collectible in the last few years due to its similarity to early big crown submariners. It is powered by an ETA 2452 and it keeps good time. Service history is unknown. This is a watch from the transitional period between radium and tritium lume. I have tested with a Geiger counter, and this does not read as radioactive. Comes on a tropic rubber strap. I'm aware that I'm a first-time seller on here and that comes with a buyer taking extra precautions. I'm happy to FaceTime and show the watch that way. Price includes insured shipping in the USA.
