Large Seamaster with cal. 50x and jumbo ref. 2861

[mac_omega]

Hi all,

I am looking for Seamaster in YG (solid gold preferred but gold capped also accepted) with cal. 501 or 505 only (no 503 or 504 because I don´t want date).

Possible references:
2854
2920
14368

And looking also for the jumbo ref. 2861 (cal. 491) in rose gold only
