Unless you know the exact watch someone wants to find wrapped up in a box with a bow — down to the precise movement and particular strap, and done up in their metals of choice — your best bet is to buy a piece that you know will stand the test of time.  That is, one your recipient won’t look at five or 10 years from now and think, “I can’t believe I ever wore that.” In this category of perpetual style, Bulova has dozens of timepieces that fit the bill.
