So, I purchased a Fortis Vintage Automatic Swiss Watch. But I don't have a reference number, model and I would like to calculate the value, because it has a very weird copper colored movement, that I've only seen in Omega's. Also I purchased an original Fortis Ostrich Leather strap, to add a bit more value to the watch, because you can tell the seller in order to sell the piece he placed any ordinary "leather" strap.
Once I install the Ostrich strap onto the watch it will look like a Men's 903.21.12 LO.38 Tycoon Date Analog Display Automatic Self Wind Brown Watch. But with that vintage look of the Vintage Incabloc. I am not sure if this is an Incabloc. So, I need to know if there is anyone here that knows the model of my watch, and which is the value, adding the Fortis original new ostrich leather strap?
Attached you will find the images, thanks in advance people!
