A wooden mallet would work fine too as it would not damage the metal surfaces. Personally, I used the nylon side of the mallet I have as it will also not dent any metal surfaces.
In either case however, the mallet would only get the pin in a certain distance - the remaining bit has to be still forced in by a pin. As Cazalea has pointed out, a screw-press would likely be the most convenient tool for this job to be honest!
Any form of plastic/paper wrap would do the same. The tape that I used is meant to mask off surfaces before spray painting (i.e. hobbyist tape for airbrushing), so it doesn't leave behind any adhesive residue on the surfaces. It is quite a niche product however... I believe kitchen cling-wrap may work as well.

You did a great job explaining both the process, and the cautionary approach to avoid damage. And congratulations on the new watch - I love titanium GS watches (but I guess you guys know that). If you don't mind, can I add a couple small points? Overall, ...  

Thanks Cazalea for the insightful comments,

Having the bracelet off the watch is always preferable before doing such work. However, given that these kind of bracelets like on the GS would require some proper tools to prevent scratching the lugs (e.g double springbar forks), I did it with the watch ... 

Another tips...

Perhaps you could use a wooden mallet to hit back the pin into the bracelet. It's sturdy enough to hit the pins but soft enough to not scratch the bracelet. And uses a thick wrapping paper than a tape instead to prevent any glue sticking into the bracelet...
