$15,600 is a pile of cash for a watch with a pretty basic alarm. You can pick up a GO Senator Diary used in steel for under ten grand, and that has both 24-hour and full-month setting modes to alert you any time of day up to 31 days in advance. As much as I've loved JLC over the years, the GO seems like a better option. You really need to *love* the look of the JLC over and above functionally superior options or be wedded to the impressive JLC warranty offer in order to make this call in the Memovox's favor.
Best,
