I've been looking for a sporty chrono, most likely aviation inspired. Want to keep the cost down, around $500 if possible. Most of the mechanicals in that range seem to use the 7750. They all seem to be pretty thick though, 15+mm, and pretty heavy (I've been looking at the Hamilton aviation line, X-Wind, X-Copter). Since I'll be wearing this on weekends, and I'm pretty active, I would prefer something not as heavy. I also on occasion wear casual button down shirts, so I would prefer something that isn't so thick that would be an issue with the shirt cuff, less than 14mm would probably do. Does anything like this exist, or is this just the reality of chronos?
