It's not an investment, it's a splurge.I don't understand why people would invest in the casing or bands on these watches. The value of the watch is in the technology which is obsolete one to two years later.
I've upgraded every year since S0 (didn't get the solid gold Edition though, haha!!).
The first year they offered a Ti casing, I couldn't get my money to them fast enough. I love Titanium.
Got natural Ti for S5, then SBTi for S6, then back to natural Ti for S7. You better believe I'll get the 'rugged' edition if it's in Ti again. Heck, I'll get the rugged even if it's not in Ti, just to have something different this year, haha!!
