If the product was a football orientated clock / football shaped clock, then football clock / ball clock is ok specifically for this concept. I can't get around "football o'clock", personally

A brand surrounding the readiness, time, information ...or other use related to football, the following alternatives would be more accepting, in my opinion

FOOTBALL TIME
BALL TIME
FOOTBALL NOW
BALL NOW
GO FOOTBALL
GO BALL
FOOTBALL DAILY
BALL DAILY (DAILY BALL)

BALL247
BALL365

(Or similar)

Alternatively, if you had just "O Football" (Oh, Football!) / O Ball (Oh, Ball!) ...the "oh" indicating a range of emotions, it would be a pass, for me ...or even in your case, a quirk on "o'clock"

The only domain name with ''o'clock'' I would ever buy would be fiveoclock (famous British term of 5 o'clcok tea drinking). Other numbers will be valuable too, obviosly. But apart of that - pairing other words would be rather hard to find a resale value on such words...

I am British and never heard that in my life. And I drink a lot of tea. wineoclock.com apparently sold for $7,500. I will develop it myself over time if no interest. You can buy Tshirts that say FootballOclock on them however I think referring to American football. Thanks for your feedback though.

I think you're the end user for this one. GL with it.
