Very impressive watch. The perpetual calendar is electronic obviously. The bezel works great. The lume is much better than expected. It's my first titanium watch and I'm liking that. The local time option is awesome since I travel a lot, it makes it easy to switch time zones and back again. It's also great that it is solar and I don't have to replace batteries every few years. I do have one complaint. It appears to have a mineral crystal and I've managed to scratch it already. Overall great though.
