Finishing the ‘bullhead’ style of 8110A chronographs today, with the fully stainless steel 67-9356. This model is instantly recognisable by its hexagonal case. With either silver/white or black dials, mine is the latter. Although not in perfect condition it runs very well indeed – it was serviced by Brian Leiser (aka 31 Jewels) so it has been in the right hands 🙂 (Ed: I said this was on its original solid link bracelet when I first posted, but this was wrong – it’s actually on a folded steel bracelet in a similar but not original style. Got carried away with my cutting and pasting I reckon! – apologies for the misleading info)
Since this one is all stainless, it is a much more hefty piece than its alloy cased siblings. The lighting in my pic looks like it has a black bezel and black applied Citizen logo – it hasn’t of course!:

Good examples of these are hard to find, and are sought after by collectors. Here is more info about this one with better images: https://sweep-hand.org/2015/01/27/this-weeks-featured-watch-67-67-9356-chronograph/
Thank you, Stephen!
