1959 Bulova 23 'XW'
Yellow gold case and back, 10K RGP, dated L9; white dial with yellow gold accents; 10BPAC selfwinding movement dated L8; hidden crown, original band likely was an expansion type based on the ad, beige strap added.
Offsite ads: 1958 and 1959
Agree with Bulova 23 "XW"
Sometimes a strap just looks better......This is a very nice watch, I really like the dial.
