WTB : Heuer 980 Quartz

Hi all.
I'm looking for a Heuer(no Tag Heuer, only Heuer) Quartz diver/submariner.
My budget is about 450-550 USD depending on condition and box/papers/bracelet etc.
Preferably with a service history. Looking at 39-41mm. Bracelet or not doesn't matter much to me.

Hit me up with what you have!

I'm based in Singapore, can deal via paypal. I have bought and sold items on watchuseek as "sdre" you can search or pm me on watchuseek via there and I will reply.

Thanks for looking!
