Tudor vintage. What model might be ?

[NTK]

Hi guys. I’m curious about this Tudor I got. I’m not sure the model number or something  like that to try to estimate a market price. Any help is really appreciated.

The caliber might be under the dial.

 Going by just the bridge layout this is an FHF 30-1 , Rolex made high grade pieces with its own designation Rolex 59. Tudor also made fine and adjusted pieces.

 Providing the balance complete is the original one and is untampered with,  you wouldn't want to sell it, but in case balance has been re staffed, you ought to check how well the balance complete has been rebuilt, or if balance complete has been repalced then its grade and adjustments made is important.

Let see a tg display of how it runs.
