Hey Zulu this isn't a forum full of noob rep collectors mate we have all been around the block and back.
Seriously read up a little more here and gain some knowledge then you will start to see what you have posted and especially those Tags are all horse$hit.
The one on my watch is for one of the other watches in the windrider series as it is 18mm at the clasp instead of 20mm on the Chronomat Evo.
You can find them on ebay for around $6-700 dollars which is still a fair bit of coin.
All good frank
Xel you need a Lello datewheel which are pretty rare to find these days or grab a junker Breitling that sometimes appear in the for sale section and just use the datewheel.
