Tissot PR 516 1966 Crown Part Number Help (Cal. 784)

TIMElyBehaviour · Nov 17, 2025

Hi guys,

Yay a tissot forum!!! So happy that we got this sub forum. Thank you to the management for this.

I have a 1966 tissot pr 516. I need to know what the part number for a replacement crown is.

I couldn’t find anything and neither could AI.
I have been restoring it bit by bit and am ready for a crown.

Any help would he appreciated.
Also is this the right buckle? I had it in my spare parts and it fits the dial font but I don’t know if it was for this model.

Sorry it took us so long! This reference looks almost exactly like the Omega Geneve Ref 166.041 case and that movement also looks like it might be the Tissot counterpart of the Omega Cal 1480/1481 that was around in the 1970s.

Almost like a sister watch to the Geneve.

The movement is the 784. The omega equivalent is the next version made a few years later in the early 70’s. 2481 or something like that.
