Fantastic collection. Very diverse one as well.
Really nice collection, well done! I like the variety of brands and specific styles, there is good range in there.
A brand that does some really interesting pieces, extremely good value for the money, is Louis Erard. I would check them out.
I’d also consider some higher horology pieces as your collection grows. A. Lange, H. Moser, and others. A Lange 1 or any of a variety of the Moser pieces would complement your current collection nicely.
Finally maybe something green? There is a lot of different green out there. I recently got the JLC Polaris Date in olive green. Outstanding piece if you can track it down and seems like it would fit your style.
That is an absolute monster of a collection. Very well done.
Really nice diverse collection, in terms of higher end vs lower end, color, style, etc.
I like them all, but lately I have been drawn to the IWC mark 18 / Hamilton style more and more
