Congrats mate, the 2225.80, the blue version of that watch was actually my first ever Omega, and one of the most solid and bulletproof chronographs you can buy. I actually wrote a review of it back here: https://omegaforums.net/threads/seamaster-professional-chronograph-review.117/

One of the more impressive features you might not be aware of is that these watches are among the very few chronographs that have fully water resistant pushers. Normal chronographs you can only use the pushers while on the surface as the seals are not designed to be able to keep water out when they're moved underwater.

The Seamaster Pro Chronograph, like the later Planet Ocean Chronograph has a special pusher system that allows it to be used safely underwater right down to its 300M rated depth.
