Thanks for the welcome. Yup, I did think 11/11 was a lucky find.
Why Zenith? Simple reason is I didn't have a Zenith in my collection yet and I was looking for a unique piece from Zenith to buy.
But importantly I feel Zenith is under appreciated despite have a solid pedigree and manufacturing history since 1865 - one of the true "Manufactures" like JLC, but who got sidelined by the heavy marketing genius of Breitling, Panerai, IWC, Rolex, etc.
So when I read about this piece and chanced upon one on sale, I jumped at it. Of course, the size was a bit of a concern, but it doesn't wear too bad on my wrist.

The Collection before the Zenith came in -
Hamilton Khaki X Wind, JLC MC Extreme World Chronograph, Breitling Super Avenger, Rado (wife's), Eterna Kontiki Diver, Omega Railmaster XXL, IWC Portugieser Yacht Club in RG, Omega Seamaster Master Co-Axial (wife's), Marathon Le Grande Plongeur, Panerai Luminor Marina 422, Radiomir Black Seal 287, Casio G Schock GPW 1000.
