Hi guys,
I just found this topic. It does not seem to be active.
But nice to see that this watch still interests people !
I live in France, and I own three of these watches.
Concerning the question of injecting a video signal into the watch, the best is indeed what was proposed : the use of an RF modulator, the RF output being connected to a jack.
Sound can be retrieved by modifying the jack connection.
I also built the converter of the german guy, but the picture is not as sharp as with the original tuner.
I needed to look at these problems because in France, the analog system is
secam, which is 100% incompatible with the
NTSC tuner of the watch. So, if I wanted to ever see the watch displaying any picture, I had to find a solution ...
I will post some pictures of my watches and mods.
