Here we have a N8 automatic daydate watch with an 17 jewels ETA 2879 movement (above the numbers are also the letters CW shown, the ETA sign is left of this). It says dual-day and automatic set-o-matic on the dial. It comes with an original Bulova, guess goldfilled, watchband (is not stated on band nore on case or back). The daydate has a quickset and two languages: french and english. No Bulova crown. Back has N8 on it. The crystal is 30mm, case (without crown) is 35 and 40mm lug to lug. I had the movement completely overhauled by my watchmaker Albert Koopman and a new crystal was placed. N ow I only have to polish the case and band. Some specifications of the ETA caliber from http://ranfft.de website Features automatic sweep second day: quickset, 2 languages date: quickset
