Lovely 40mm pilot's calendar watch. Excellent finish on the case and bracelet; very fine brushing combined with polished edges and bezel. The high quality crystal is hardlex with excellent AR coating inside - often the crystal just disappears and you are left with a good view of a nicely detailed black dial - other times the dial appears a deep blue. Tough too as I managed to have a run in with a wall and added some patina to the bezel but the crystal remained undamaged. I do not think I can avoid also purchasing the quartz full chrono version and the type A or B of this series by Carnival Jianianhua ^^
