Best to buy in physical shop, can handle and inspect the watch to your heart's content before plonking down cash, more so for "vintage" piece like 6694. Never know the actual condition of the watch, pictures are usually more flattering than actual watch. Shops I am not sure, maybe the pros here can recommend?

Internal movements' quality also important. Some just nice on exterior.
