Hello guys,I just acquired this Longines clock Cal. 24.41 that seems very rare, with a marble socket but it is not running. I am taking it to be checked, I would appreciate any comments. The crystal is such a good shape and it is truly a good looking clock but Im not sure if I should fix it or leave it as it is. I also have seen a clock very similar to this one but it is identified as a marine clock, even though, my clock serial number was checked for Longines with the original marble socket and I doubt it is a marine clock.I would really be thankful for any info since I am not a watch expert. I heard that the 8-days marine clocks are rare, Is it this clock 8-days?ElÃas.
