Hi, I would be very grateful for the thoughts of forum members on this Moonwatch which I am informed is a 145-022 69 ST. Sorry, the photo is not great but I have seen it briefly in the flesh and it does have a stepped dial and a hippocampus on the case. Disl and hands both have s nice patina. Has been offered to me for £2300 from a bricks and mortar store, no box or papers. My research suggests it is genuine but I am no expert and new to the vintage market.
