Omega Electrogolf ...?! Never heard of such model! Uncle Google doesn’t know anything.... Do anyone here knows more? There are recently 2 of them on yahoo auctions, one with a bracelet one with strap. This one with the bracelet has an engraving on the back ... S49. 10. 18. (Showa 49 should be 1974) https://page.auctions.yahoo.co.jp/j...crt&cpt_n=127_10012_10005_159938#&gid=1&pid=2
Here’s the second one. Looks like the engraving was lathed down?! Sadly no shot of the inner! Maybe a f300 ?! here’s the link: https://page.auctions.yahoo.co.jp/jp/auction/1000874022#&gid=1&pid=1
In Japan, when a hole-in-one is achieved in golf, for some reason, the person who achieves it may send a congratulatory gift to a golfing friend or other person as a memento. (There is even hole-in-one insurance for that!). Perhaps the engraving on the back is a commemorative engraving of the hole-in-one. The name is the name of the person who made the hole-in-one, and the date is either the day you made the hole-in-one or the day you gave this watch to your friend as a memento. I don't know much about ELECTROGOLF. There have been a few ELECTROGOLFs sold on Yahoo Auctions in the past. I agree with you and think it is a variant of F300. I guess I just changed ELECTQOUARTZ to ELECTROGOLF.
It's a handsome watch, but I think I'd get annoyed reading that word 'Electrogolf' every time I looked at the dial. It seems to date from that innocent period in marketing where you just combined two features of a product into a new word. 'Ladymatic' is another, but I think that's so bad that it's good.
I've had one of these in hand. It is just a f300 variant, nothing special. The one I saw was a Japanese import so I guess as noted above they were a thing there for lucky or unlucky golfers.
The case back engraving of "Omega Hole in One", haven't we seen that on Genve Chronostops in the past?
The Electrogolf also gets a mention in this thread by Silverhawk of Electric Watches https://thewatchforum.co.uk/index.php?/topic/108474-omega-constellation-electronic-chronometer/
I've seen them on yahoo japan. I am pretty sure it is a different branding for F300 series tuning fork watches. They are scarce, but nothing special besides the name.
