WTT: Universal Geneve Tri Compax for a YG 1803 Day Date

Wanting to trade:
A 1,34m serial UG Tri Compax (1946-1949) which just had a service. Comes with new strap and (a(?)) original UG box. Watch is in nice condition but certainly not perfect.

Looking for:
A (yellow gold) 1803 Day Date. This is a project watch so condition of dial/hands/movement (in need of service) is not important. Neither are B&P or a bracelet/strap. Case must be strong and bezel preferably as well.

Trade value of my UG is EUR 2.500/USD 3.200. Limited money up or down is ok.

Return: if item not as described (same will go for you).
I live in the Netherlands and have dozens of references. I expect the same of you (or you'll be sending first).
