indeed not similar and that exactly make them into a 'collection' of its own 
I always imagine if I can only have extremely limited watches, what will they be?
After some extreme thinking and editing, I know that they must be wearable, highly functionable and pleasing to the eyes.
The Milgauss is the best 'daily beater'....as it is in metal bracelet , tightly waterproof, suitable to be in any climate condition.....and at a price point that will
not hurt the bank or make me worry that it is bang on any object. It is a watch that one wears and go, very simple, very casual , very relax and yet something special.
The URWERK (also a stainless steel) is one good conversational piece that is highly wearable and very chic looking.
It shows a very casual chic character. It has a dashing appeal. It is also a very simple watch.
Both watches tells time only on the dial and none has chrono function.
The Third watch that falls into this category must also be simple and it should be more classic looking.
And it has to be what I think is 'the best' in that particular selection....so far I shortlisted Kari and Dufour.
Thank you for reminding me Kling 
I'm very interested about his watches. Can you pm me where to go about getting his watch?
I have tried quite a few watches I love and I think I'm getting near finding my ultimate 'keepers' collection ;-)
I hope so...hahhaha
The fun for me in this hobby is to have a highly focus and yet extremely wearable (meaning they can be oftenly worn) collection.
