Omega Ref. 7151 “Maille d'Or,” Gilbert Albert design

Hello all,
I've been a regular poster on TheWatchSite and have had a few of my Seikos serviced by a regular on that site. Currently I am trying to gain more info on a watch which was my mother's:

Omega Ref. 7151 “Maille d'Or,” Gilbert Albert design, approximately 1966–67, 18K yellow gold, Cal. 650, 17 jewels, integrated 18K gold mesh bracelet. Original box

Using Chat GPT I've discovered the details about the watch and would welcome any more detailed info on the watch. I have attached pictures for your assistance. Looking forward to hearing back from you all.

Thanks, Josh
