Jumphour watches - the flip clock of digital watches?

The 1960s and 70s saw the rise of the "jumphour" watches - watches with normal internal movements but with rotating discs displaying digits instead of hands. The watches were an less expensive alternative to the fancy new-fangled electronic digital watches that were coming into fashion (if you can call those clunky watches fashion). The watches were commonly called "jump hour" due to the quick switching of the hour disc, reminiscent of flip clocks, in my view.

One model of jumphour watch was the swiss made, Haverdigit watch which was advertised for $12.95 in the March 4, 1974 issue of TIME magazine. $12.95 would be about $67.67 in 2017 dollars.


Text from the advertisement:
How you can get a fine digital watch, tell time at a glance, and find deals galore for just $12.95.

Let's face it - most often when you look at your watch you don't relly know what time it is, because you get only some approximate impression of the position of the hands. But this cannot happen with Haverdigit. Because Haverdigit gives you direct digital read-out, which means you know exactly and at a glance that it's 1:17, rather than sometime between 1:00 o'clock and 2:00 o'clock. Haverdigit is our exclusive Swiss import. It features silver-toned steel case, tropical strap, a fine Roskopf movement, and a strategically placed jewel - just to keep it running and humming smoothly on and on. And, of course, Haverdigit is an almost laughable bargain - similar watches sell for $25 or more. But that it's all: we'll also send you our colorful 64-page Catalog, which is absolutely chock-full of good deals PLUS a $2 Gift Certificate that you may apply to your first purchase. One more word about Haverdigit: you may return it in two weeks for a full refund if not delighted (and still remain our friend). And it's guaranteed one year for manufacture's defects (we repair or replace free, of course, only charge for postage and handling). So fill in the coupon, send us your check and let us shoot that Haverdigit right out to you. Watch shown 20% larger than actual size.

Yes, send me Haverdigit. My check for $13.95 ($12.95 plus $1.00 for postage and insurance - California deliveries add tax) is enclosed. haverhill's 584 Washington Street, San Francisco, 94111
