This is what we call good timing: Just as the country is starting to take watches as seriously as Europe does, ubiquitous local watch retailer Alpha Omega opens a new high-concept store and fills it with the world’s most sought-after timepieces. With gleaming cases of wrist candy from Rolex, Gucci, Tissot, A. Lange & Söhne… it’s a timekeeper’s utopia and every big shot’s bliss. (No one there raised an eyebrow when Ben Affleck walked in to buy a Vacheron Constantin.) Still hunting down that elusive Panerai? You’ll find it here in the heart of Harvard Square, along with freestanding boutiques and fine jewelry from Montblanc, Bvlgari, and Doris Panos, plus lower-cost and sport watches.
