Here is a detailed look at the Seiko 6S37 movement, which is [somehow related to] TAG-Heuer's recently-introduced Caliber 1887 movement -- The Flight Master was on the deck, or something like that.
you will see some areas where the movement is praised; others in which there seems to be room for improvement; we can hope that TAG-Heuer will enhance and improve this movement, as it prepares to launch the new watches that will use this motor. Personally, I am excited to see this new movement and, of course, the watches themselves.
