Hi chaps hoping you can help 馃榾

I'm looking at a two tone 980.020.L Heuer 1000 from Japan and communication is quite hard with the seller. There's plenty of photos but nothing close up of the crown (I can see it's silver but thinking the plating could have gone).. whilst i'm waiting for the crown photo could somebody help me with what type it should be?

My guess is screw down, gold plated and Heuer signed?

Apologies for the rubbish phone screen shots but that's all I have at the moment. My first thoughts were that the crown should fill the crown guards more?

There have been 2 crowns used in that time area for the Heuer 980.020L, the bajonet style screw-in (trouble) and a normal screw-in one.
The bajonet style is signed "Heuer" and the normal screw-in one is blanco.
For more info about how they operate, see the pictures I just took from a Heuer manual and a supplemental instruction:
P1240617.JPG P1240618.JPG


Why is the bajonet style trouble?
Most of them have been broken by their previous owners either due to not knowing how to operate them correctly or just bad design, and do work now as a push in crown, screwing in does not do anything to secure it, and it will surely pop out when you are not aware of it, so the watch is not waterproof at all. To repair, find a good functioning "heuer" signed crown, which is obsolete and finding a working one is a needle in the haystack so to say, or replace both crown and crowntube to the later style TAG Heuer screw-in crown. Cost around 50-100 USD, depends on watchmaker.
Succes!
