I am looking to pick up a new Marvelight and just wanted to get some info with regards to the Engineer II and III before I make the purchase. So far the only info I have found on the new Engineer III is that is has increased resistance to magnetism at 80,000a/m versus 4,800a/m or the Engineer II. Are there any other technical upgrades or changes that were made to the Engineer III? I am interested in the blue dial and want to know if both models have the same shade of blue or do they vary slightly? Any input would be a big help. Also if you have any wrist shots please post them as I can't decide on a dial color and wrist shots will make my decision easier.
