A bit like Altair i to have a bit of a monthly thing when it comes to my watches, though not as time consuming...
I like to take all the watches out and set them all to the same time. I also look at how much time the watches have lost/ gained, overall its good although the skyland has gained about 3 mins.... oh and give them a good old polishing.
I always cant help but take a cheeky photo...
I love them all! they all have there own little uses:
Hour Vision - Perfect with a Black shirt/ tight cuff shirts.
Planet ocean - fantastic everyday were, such a clean dial.
Skyland - If im feeling loud and want something heavy on my wrist for the weekends.
Tag - Perfect for the ruff days out climbing or cycling etc.
Seawolf - BIG but yet not to showey, another amazing everyday watch to change to - Probably my friends favorite.
Zenith - My proper fancy watch! the one that only watch people understand.
Also i have done a short video of my hour vision
. If you turn your speakers up you can actually here the balance wheel resonating through my chest of draws.. wich is odd, non of my others do this. You will notice aswell, due to the Heigh'ish beat its more of a metallic hum ( by the way its upsidown because the mic is on the top of the camera
