For a handful of Weems collectors, the 33mm Weems made for the American market "LXN"
is a bit of a grail watch. The more well known midsize Weems is the 34mm British
RAF 6B/159 VIIA watch. There are many of the RAF Weems, but the American versions
are earlier only made in 1937.
These are American market midsize Weems. I have no idea how many were made.
The center and right are both no lock Weems. It took some effort to find proof these
existed when P.V.H. Weems ordered them in 1937. We found in one of his books he
published pictures of a early example Longines-Wittnauer Co. The serial numbers for
4 different configurations are all within a few hundred serial numbers. So there was
a rapid development of these as several different bezel locking mechanisms were
tested. You could speculate that these were the prototypes for the RAF version.
The center watch is the most interesting since it is both a no lock bezel type and has
a gilt print US Naval Academy at Annapolis logo that was printed by Longines. I have
only seen one other of this dial. They are hard to track down.
