I bought a black dial and a grey dial, and the grey dial has this same problem. I asked about it as well but got no response. The black dial movement crown feels great, but the grey dial crown takes a LOT more force to get it set back into the case, and often the date adjustment does not disengage. Seems to be a hit or miss problem.
Same thing happened to mine. I sent it to Katt & he fixed it. He serviced it and replaced a few parts. Works like a champ now.
