Two-Tone 10K Gold Filled case.

Can't seem to ID this one... any suggestions?

Added "F" designation as this watch follows all criteria in adverts, page 8, image 19. Will update with more pics and info when watch arrives. In need of a lot of work to case, but watch is running. 1 fifth second gradations to dial register. Radium numbers and hands, red seconds hand.

EDIT:- Caseback will not come off, so looked further and the bezel is removable, as in pics. Could not take out stem as should come out in two parts, male and female, but won't. After letting mvmnt. drop partially out, I could see inside for info, and caseback reads, "BULOVA WATCH CO. SWISS, 53,   246166."  L3 on mvmnt. BXW, 10 BUC, 17 jewels. Running smoothly and keeping very good time. Length lug tip to lug tip is 37mm. Width minus crown is 30mm. lug gape is 16mm.

EDIT:- Name change to "Seabee" as watch is on leather strap, as per 1953 ad. 

1973 (N3) Case and 11AOACB 23J Movement. Beautiful dial and hands...interesting mint green and dark brown hour marker colors. Very heavy electroplate gold case with 10k rolled gold plate back & bezel. All original. Looks very similar to a "Men's Lib" Version 3 - Senator "F" from the 1972 ad. 

The movement originally was a square symbol but due to major overhaul I canabalized parts from a 10AE Omega movement. The case is a gift from Mark of Fifth Ave Restorations and I shall be forever greateful to him for his generosity and help in seeing this watch come to life. The crystal is glass and makes the watch standout so very well. The case received major body work by me to make it suitable for the movement. The dial is original and will not be redone. This has been the most challanging task I have undertaken so far in my short time as a Bulova lover and all work has been done by me. This is my favorite watch and will be around for many years to come (I hope).

Thanks to all of the many people involved in this project. The ID is watch L of the ad .
