I've had mine for a little over three years now, and I have zero regrets! It's a wonderful timepiece, based on a classic reference that has its own great history. The mechanical movement learning curve is pretty shallow - the Caliber 1861 movement is a stout one with 48 hrs worth of power reserve and is very reliable; literally, its wind and go.
As for weight, I guarantee you that you'll acclimate within a couple weeks at beast.
The only gotcha that I feel needs to be pointed out is that the lug width is 19mm instead of the more standard 20mm; if you are the kind of guy who likes to swap straps, this somewhat limits your options.

As for "babying it", I never babied mine, and she is a daily wearer whenever it's in the wrist-time rotation. I'm pretty aware of it whenever it's worn, and that automatically makes me don't-flail-your-left-arm cautious. It's got some marks, and it's taken em with grace. That picture I posted was taken yesterday.
Note - I'd be remiss to not mention the following. The FOIS is a space-themed watch, based off of the precursor to the famed Moonwatch thatbisbthe Speedmaster Professional. While that 42mm beast didn't work out for me, I still encourage you to at least glance at the hesalite version before settling on your decision. THAT is the iconic Speedmaster.
Hope this helps.
