    Omega electronic fz300Hz questions

    Happy Friday Everyone!

    I have an Omega electronic fz300Hz that I bought many years ago. I would like to spruce it up a bit and make it more "original". First, it has a generic crown on it. The crown that's on it is 4mm. Would any 4mm Omega crown work with this watch?

    Second, I need to replace the day-date wheels because that function doesn't work. Would day-date wheels from a Bulova tuning fork watch that is approximately the same size with the same day-date configuration work? The window that frames the day-date on the Bulova doesn't have a divider in it. However, the Omega does.

    I just had the movement serviced and it works very well. I haven't checked to see what the exact -+ is per day, but it hasn't changed much since I got it back yesterday.

    I'll post pics of it later.

    Thanks in advance!
    Have a great weekend,
    Chris

    I had an Omega 300hz and I learnt that they do chew up their date wheels, mine was replaced by a nos Omega item but if the Bulova is the same size then there is no reason why it should not work, and I guess any Omega crown will fit too if the stem size is the same?

    No, the Omega with day and date is actually an ETA-ESA 9164:
    bidfun-db Archive: Watch Movements: ETA-ESA 9164
    This was designed using a Bulova license, but else has nothing common with any Bulova hummer.

    The ETA-ESA 9164 was applied by many brands and many are killed by wrong disassembling and assembling for servicing. Accorsingly not running donors can be found for few bucks.
