The perfect watch: Smiths is the "only" company that can do it.
This is the perfect watch, and the highest likelihood that any company will make it is Smiths, because Smiths has watches that fulfill every criteria, EXCEPT one:
Criteria:
1. small, less than 40mm
2. antimagnetic (either a shell, like Smiths does, or antimagnetic hairspring)
3. Sapphire glass
4. 50m WR +
5. no date: I like the casual aspect of pick-up-and-go no-date watches. I don't need the date anyway since I carry a cellphone. Plus imagine if you had a 3 hander no-date at a transit airport: to sync the time to the local TZ is as easy as setting the time backward or forward, and it would be very quick to do. If you had a date and you were going backward several TZs and you were doing it between 9pm and 3am, you would have to set the time forward after 3am, set the date forward 30 days, then set the time forward over 20 hours to the right TZ.
6. hand-wound: automatic watches are not suitable for running and biking because of the stress on the rotor from constant vibration, and the rotor constantly stressing the mainspring.
7. 12 hour bidirectional bezel: technically you can use a 0-60 bezel for 1-12, but when you are tired at an airport, you don't want to mentally calculate what the timezone is. I find it easier to use a 12 hour bezel to substitute for a 0-60 timing, than using a 0-60 bezel substituting for 1-12. Plus it should be bi-directional, because the reason for most bezels being unidirectional isn't really an issue for most use cases - it's only needed for the life-threatening purposes of diving, which doesn't apply for 99.9% of real-life uses of the bezel.
So in other words, Smiths has the PRS-29, which fulfills criteria 1-6, but there is NO WATCH ON THIS PLANET that fulfills all 7! Isn't that astounding? I know I'm not crazy in thinking that a watch with all 5 criteria would make a near perfect watch, because I've been in this hobby for over 25 years, have owned over 30 high-end watches including a Daytona and from every sports watch brand I admire (Rolex, Omega, Breitling, Tag, Seiko, Citizen, Casio, JLC, Panerai, Chopard, Longines, Tissot, Oris and probably a few others), and I really enjoy the PRS-29, but I think the perfect watch would also have a 12 hour bidrectional bezel.
Smiths: please make one? Please?
