I have a Seamaster Professional 2254.50 I bought in 2009 to mark a point in time of my career, this will be my 10 years owning the watch, it has been my daily workhorse everyday but sometimes I rotate with Speedy Pro 3572.50, I recently like the look of Seamaster 300 Master Co-Axial steel version , I have a few questions :
1. Do you guys think is it a worthy upgrade to the seamaster professional? I'm considering to sell mine and invest in a new Seamaster 300 Master Co-Axial, but the 2254.50 is a classic now
2. Any idea why the Seamaster 300 is missing the Professional wording on the case? Is it something to do with the missing helium escape valve?
3. The steel ring in between the front sapphire crystal and bezel, is it easy to scratch?
Thanks in advance
