I have mixed feelings.
I was wiriting messages to CWC a few times for a few months - no response. I was looking for a display caseback for my EXPII (newest version), also for my Speedy Tokyo 2020 limited.
Not too much to discuss about EXP, since it's just a standard product of Custom Watch Concepts, but I needed to talk about Tokyo 2020. Even though it looks like a standard previous version Moonwatch case, when I wanted to order the caseback from Spralwinder, they told me it would not fit on Tokyo and there is no alternative for the time being.
I have asked this several times to THomas, have not received any reply for months.
Then suddenly out of the blue - got an e-mail from Mr Preik. He was communicating to me clearly, that EXPII is a standard product, and Tokyo 2020 - he was not conscious about possible incompatibility. So he proposed, without asking, that when I order EXPII casebecack, he would send the Moonwatch one to me free of charge just to check if it fits. Anyway, from the moment he wrote me first e-mail we exchanged probably dozen of them in the space of 1-2 dayes, Firday & Saturday.
I placed an order for EXP II caseback and after just a few days I received TWO pieces - one for the Rolex, one for Omega.
Rolex fits absolutely perfect, and even though their movement is not any piece of art it looks very nice. Omega indeed did not fit perfectly (thread was OK, but there is some problem with thickness and something else), so I wanted to send it back, I am an honest man 😀
I wrote to Thomas asking where I whould send the caseback, also tried to explain the problem asking if he could make custom caseback for TOkyo (with a chance to sell a few more, since noone elese makes them), he's been silent for 3 weeks already.
So, Mr Thomas exists, company also makes the products, but communication sucks, unless you're lucky 😉
From the product point of view, I recommend CWC 100% though.
