It’s not often that I’ve added ‘new’ variants to the Automatic Chronographs page, but I have recently been able to confirm one that I had previously been unsure of – and I must thank George, a fellow enthusiast in Ukraine, who recently sent catalogue scans to add to me reference material.
The model in question is the 4-901096 black cased ‘bullhead’ model, which was not given its own model number. I was sure about the green dialled version:
But not so sure there was a gold coloured version – until now:
This is not the clearest of images, but the case number is confirmed. So, as with the 67-9071, the 4-901096 has these two dial colours. I’ve amended the Chronograph reference page accordingly.

Glad I could help your hobby!

Hi George, thanks again – it’s always good to solve a mystery 🙂 And apologies for getting your location wrong – I’ve now edited my post to correct my mistake. Stephen
Interesting stuff, thank you. I think I saw the green for sale a couple of times, but didn’t pull the trigger because even if it’s original, this shade of green looks a bit “tropical” to me 🙂
You mentioned reference material – does it mean that there’s a page on the site where catalogs are available for download? I couldn’t locate one. Thanks!
You’re welcome 🙂 No catalogs or other material for download I’m afraid – I referred to my reference page on the blog for the chronographs: https://sweep-hand.org/citizens-vintage-chronographs/ Stephen
