***********The manual wind movement loses about 2 minutes by the end of its approximate 41 hour power reserve period with all chronograph functions working perfectly as they should. The pushers depress and release crisply. The top pusher starts and stops the sweep seconds hand while the bottom pusher resets it along with the minute register (right subdial). Both the sweep seconds and minute register reset to precisely 0. After the watch has been sitting idle for a period of time it tends to take about 17 full winds of the crown to get the movement going which suggests a service is needed. Additionally, the crown can be a bit stubborn to pull out. When this happens I'll give it half a wind counterclockwise or so and then try pulling it out again. It can be a bit of an exercise in patience. A complete overhaul is long overdue and recommended.***********

This seldom seen vintage 1940/50 Croton Clamshell Big Eye two-register chronograph has under the damaged crystal a silvery white dial that is in poor condition. The lume on the dial no longer glows after being exposed to bright light with majority of the lume on the hands having fallen out. The all stainless steel lugholes 'clamshell' case shows honest wear and oxidation. The back of the top left lug has been crudely inscribed. The outside of the case back is stamped "CROTON - WATERPROOF - SHOCKRESISTANT - STAINLESS STEEL - INCABLOC." The crystal needs to be replaced.

While I normally show pictures of the movements of watches I put up for sale I won't unscrew the screws to remove the case back on this watch. As clearly seen in the pictures all four screws are present. The manual wind movement runs strong, albeit slow, and all chronograph functions work perfectly as they should. The pushers depress and release crisply. The top pusher starts and stops the sweep seconds hand while the bottom pusher resets it along with the minute register (right subdial). Both the sweep seconds and minute register reset to precisely 0. After the watch has been sitting idle for a period of time it tends to take about 17 full winds of the crown to get the movement going which suggests a service is needed. Additionally the crown can be a bit stubborn to pull out. When this happens I'll give it half a wind counterclockwise or so and then try pulling it out again. It can be a bit of an exercise in patience. After recently winding the original non-screwdown crown 30 full revolutions the movement, with all chronograph functions running, lost about 2 minutes by the end of its approximate 41 hour power reserve period. The crown winds with an appropriate amount of tension. A complete overhaul is long overdue and recommended.

This watch measures approximately 34 mm excluding the crown, approximately 36.5 mm including the crown and approximately 18 mm between the lugs. Case thickness, measured from the bottom of the case back to the top of the fixed bezel, is approximately 9 mm. Including the crystal thickness measures approximately 11 mm. The lug to lug distance measures approximately 43 mm.

A complete overhaul is long overdue and recommended. As such there are no warranties, express or implied, attached with the sale of this watch. Vintage means old and while my personal belief is that old-school means better quality and workmanship, things can and do go wrong from time to time. Any servicing costs going forward are your responsibility.
