I looks like Sam Neill is wearing a Citizen Promaster Marine Automatic NY0085 watch in Apples Never Fall (2024).
This is not yet confirmed, but the images we have show a diver's watch with the crow on the bottom left and a black and red bezel. similar to the Citizen Promaster Marine.
The strap is not the original rubber or metal strap but it looks like a custom added black leather strap.
