My advise is go to the JLC Starhill boutique and pick out a few that you are attracted to.
Try them all on, ask the boutique manager any questions you want on the movt, complication and then make your choice.
Her name is Nida and she is very helpful.
If after doing that you are still uncertain, take down the names of those models and post up your questions here again.
JLC owners will be able to give you THEIR personal and individual opinions for you to make the final choice.
