Hi Martijn,
Here you go, it came with a steel diver so I don't know where it was sourced from originally, but it does look good with the yellow on the carbon diver.
You'll not need to, but if you do I suggest a watchlsmith. I changed the insert on my TC LV (from black to green) and my TC Cadell Rouge Sub from black to red. Both times I struggled to remove the insert. Eventually I used a soft plastic tool between the crystal and the insert and it just popped out. I managed to insert the LV myself but the red needed a trip to my friendly watchsmith.
I've been here a year today and only three hundred odd posts, but I've made some good friends and have pocketed around 50 watches - one per week
So thank you to all the great members here.
Most if not all of the TD's can get the same watches. Pick the seller first then the watch is the golden rule, but yes Andrew at Trusty is good to deal with. And, welcome BTW.
