The soft calf leather strap complements the smooth edges of the O-case just fantastically. The silver case with white dial is the clean option for the office and of course the rest of the day as well 🙂

Product Reviews

  1. I'm SLOW cause I retired. by Bob Davidson

    Works great, perfect for telling RETIREMENT time! Heck, I'm always 30 min early for any appointment any way.

  2. Makes me feel more connected to a day as an astronomical phenomenon. by Karl R. Kaiser

    I like being able to visualize the day in one sweep of a "day hand" on the watch. And if you set the time carefully you can tell the time within 3-4 minutes, which is close enough for anybody who doesn't "wait 'til the last minute". Also for those who are astronomically-minded, if you point the 12 south and angle the face of the watch parallel to the equator (or the central axis pointing to the north star - parallel to the north pole) then the watch's single hand will point towards the sun's - day or even at night, when the sun is "under" the Earth.

  3. Putting my day into perspective by Suraj

    Putting my day into perspective, this watch is a masterpiece. Swapping the default strap with a nylon band has made it vegan-friendly.

  4. SLOW O 04 Watch by LifelongAtheist

    It's different, and it takes a little getting used to, but I like it. My sons both think it's too cool for me, and they're probably right, but I'll keep wearing it anyway. I'm glad I bought it.

  5. Transformed My Relationship with Time by Alan in Boxankle

    love my slow watch; it truly has transformed my relationship with time. If I need to know the exact time, I can always look at my smart phone, but I've discovered that as a college professor, I rarely need to know the exact time, other than showing up to meetings on time, of which my phone reminds me, and pacing classes, for which there's a clock on the wall as well as a computer display. Anyway, if I really need to, I can gauge the time on my slow watch within three or four minutes as this particular model is very easy to read, but again, I rarely need to. Wearing my slow watch, I find on the one hand that in general time seems to move more slowly while on the other hand I now tend to be more punctual for classes and meetings. And as others have noted on reviews of other models, I just don't need to look at my watch as often. It's really hard to explain without actually experiencing it. Note that you do have to follow directions in setting it to ensure consistent accuracy.
