In fact, I think that's a very smart way to own the watch. The cost of PAM72 + spare strap + buckle would be far cheaper than the cost of PAM74 + spare bracelet.
And you now have the flexibility of wearing the watch w/ the brilliant bracelet or strap!
Not to mention the fact that I think the original design bracelet was in a class of its own. The current bracelet design does not even come close.
Soon people should realize the importance of the zenith heart!
Bravo my friend!
