In hand and on wrist, both watches are big, heavy, and feel very special. Of the two, I definitely preferred the Speedmaster Chrono Chime, not only for its familiar good looks but also for the lovely combination of the aventurine dial and the guilloche finishing of the sub-dials (which I think looks fantastic). While certainly wide and quite thick, the weight left the most notable impression on my wrist from either model. If you don’t mind a large watch, I could see the Speedmaster Chrono Chime being easy to wear once you’ve properly sized the tapering bracelet and entirely recalibrated for the raw heft of all that gold. Again, the movement alone has more than 45 grams of gold.
