I can’t recall the specific references, but yes there are a few different dial variations, but they are clearly a very close imitation of the 6105-8000/9 case and style.
Realistically the originals can be had for under $2k in very good condition. And decent examples can be purchased at auction for $1k or less, they may just need some TLC. They still fly under the radar occasionally. I just sold an excellent example, fully serviced and restored, for about $1700. Not selling any more at the moment however, because I only have one left and I really like them.
