Bulova 1951 Watertite

I believe this one is a 1951 Watertite L variant with original band and box?  Round, white color case that is exactly 31mm without lugs and crown.  Beautiful white background dial with contrasting raised gold numbers at 3,6,9,12, and raised linear indices at other positions.  Also has an attractive waffle pattern "bullseye" in the center. Gold hands with lume on the minute and hour and a sweep second.  Screw on style caseback with 51 date code and Bulova Watch Co. printed on the inside.  10 BTC movement that winds, sets, and keeps good time.  Appears to have it's original band based on the attached add from 1951. Also have the box-set and a water-tite tag.  

I've had this one for a while now and its one of the cleanest, original watches I own.  I honestly haven't given it much wrist-time due to not wanting to diminish its condition.  As always, thanks for looking and love the site!
