What The Heck Is A "Franken" Watch?

To the OP this is how I personally define it.

Franken

1. To replace original parts with non-original parts or parts from another watch of the same model from a simlar era
2. Used to deceive a buyer

Restored

1. To replace original parts with parts from another watch of the same model from a similar era or factory fresh pieces
2. Typically used by people of honest intent when it comes to sell a watch

Modded

1. To replace original parts for a particular model with original parts designed for a different model
2. Only uses original manufacturer parts.
3. No aftermarket pieces

Custom

1. To replace original parts for a particular model with parts designed for a different model.
2. A mixture of original manufacturer parts and aftermarket parts

So, your Speedy, El's SMP and S.L's speedy are Mods by my personal definition.

I had a speedy with the same dial as your's.



This is a mod.

I have this which currently has an aftermarket insert on it. It is a custom.


I made a new insert once for a SM300. Original bezel, but homemade insert. This is a custom.



This particular watch was to my knowledge a custom as I wasn't sure if the dial was authentic or not. If it was, it was a mod.
