also stamped L1 unadjusted, and SXW (or MXS) near the advance/retard pin. model is a watertite i think
Hi baron4004, welcome to myBulova. I'd say you're spot on with the ID of "Watertite". I see a couple different variants in the ads (Watertite D, F & L). This case style shows up a couple times as having no variant and once as a "D". It's a nice looking watch. I like the red sweep hand.
I'd vote to name it "Watertite" (no variant).
The Bulova Watertite 'F' is advertised as having a chrome case with stainless steel back where as the Water Tight 'D' (yes the spelling is different) is advertised as having a full stainless steel case.
From the wear on the subject watch I'd say its the Watertite 'F'.
The Watertite 'C' has a 15 J movement.
The Watertite 'M' seems to be an exact match of the 'F', but is advertised in 1953.
In later 1954/55 we have adverts showing this watch as the Bulova Magellan.
There are also a number of refferences IDing this as a Seabee when presented on a leather strap.
It also looks like it morphed in the first of the Sea Kings in 1955.
