Here is a Breitling Colt Automatic Ref A17380, the case is 41mm in stainless steel and is water resistant to 500m with stunning slate grey dial with baton style markers one of the best colours in my opinion, rotating bezel with minute markers for diving. The Breitling as most have sapphire crystal glass with anti glare coating both sides for no sun reflection when in your jet fighter!!

I have owned one of these a fair few years back good size and good weight on a Breitling Pro II bracelet.  The colt has grown over the years in size which has probably had at least four overhauls in the past to present and got better and better.  This particular model Colt are a entry level Breitling for an Automatic movement, as quartz always cheaper to buy new and used but secondhand prices are good value for money I feel.
