I`ve never seen a 166.024 with batton hands...so somebody was playing with it... the cracks are weird looking, would say relume with some relic job to make it look vintage? UV light photo may help also as stated.
Baton hands were certainly seen on early 166.024’s.
I`ve seen baton hands on US market 1968 series, but that is no date version.
If you can show me some 166.024 with baton hands, I`ll gladly extend my knowledge.
First batch of 166.024 for public was made OCT1968. The were Naiad crow equipped, big triangle, silver date window. I don`t count in the prototypes delivered to Comex, which are 1967 movements.
