Just want to share my experience with Nik. I had a problem, common one, date issue, with the 3186 rep movement on my GMT II batman, sent it to Nik, who sourced a nice VR replacement, he also managed to source a gen dial and a blistered gen crystal too. Fitted the lot and just received the watch back today. Very pleased with the result. Great service, great communication (very important), despite me being an impatient pain in the butt lol. Thanks Nik.
