One can love the watch and yet not love the business model of the company who makes them. Yours is very nice!
That my friend is the super cool Speedsonic f300 Omega tuning fork chroometer watch, with the extra cool original bracelet! It has the tuning complication, it works as long as you wish to tune to middle D.
Here's today winner, bought it second hand a week and a half ago and have worn it quite a bit in that time. Forgive the jaundiced look, I took a few photos before I realised this watch just glows in the sunlight.
