Well, basically the title says it all. The catch is that the magnifying glass is not separate, it's on the actual hand of the watch, thus rotating along with it. The watch face would include the hour as they normally do, and through the magnifying glass you could see either a color-coded or somehow simplified
notation of the minutes, along with an extra mark on the lens itself for precise reading. The watch would of course only be able to show some 5 minute increments, and you'd have to have pretty good vision to read it, but I think it would be a neat gadget.
same idea, less accuracy

one-handed 24 hour watch

At $425 this watch is a little over the top with features, but it seems to work, even without a magnifying glass. "Oops, I missed my 3:17 appt." [joking victim, Oct 17 2004]
What it might look like . . . maybe . . . sort’a

Yeah, i'd have one of these! |

Not if it were big enough! |

"Not if it were big enough", or if you eyesight was good enough! |
|

Say you have good eyesight and the magnifying glass can magnify some 0.5 mm high figures enough for you to read them (I assume the figures would "radiate" from the center of the watch, i.e. they would be vertical around noon and horizontal at 3). |

You'd have to represent 60 of these to show each minute in the hour. 60 x 0.5 = 30 mm, which is 3 cm. Let's round that to pi for the purpose of this calculation. You'd end up with a inner perimeter for the minute marks 12 x pi cm long. Since perimeter is 2 x pi x radius, that means the inner minute marking circle must have a 6 cm radius. Add another cm for the hour markings and the watch frame and you end up with a whopping 14 cm (5.5") diameter. I wouldn't wear that. |

Good link there, joking victim, it's close enough and personally I like the day/night indicator. Not very accurate--misses the magnifier, see?--, but it's pretty darn close. |

Sounds like an application for a vernier scale. 59 on the "hand", and 60 on the dial. |
|
| |
[Bristolz], You never cease to amaze me. How can you do it so fast? |
|
| |
Nice idea [gutza].
[bristolz] - freakish. + |

Bristolz, whoa! If you're keen on using your 3D skills, might I suggest checking out http://www.wikipedia.org -- they always need a hand, especially regarding graphics representation of various concepts, and you'd also put your talent to use in a nobler direction IMHO. That doesn't mean I don't appreciate your representation of my idea, it's obviously flattering. Just a couple of notes if you're in the mood to revisit the rendering: I would go with "0" instead of "60" for minutes, and the extra marking on the lens should be a lot thinner. But other than that, nice design! |

I only do ignobly directed illustration. |
|
| |
I just want to know that the other hand's doing. Or maybe I don't. |
|

"Ti ti ti" - the sound of one hand ticking. |
|

Bristolz, yes, much better. And nice comment about ignoble illustration, I can't beat that. Have fun! |
