We make a trip back to the 1970s and investigate the wild-looking Seiko 7015-6010 Time Sonar Chronograph. Lock in and appreciate the ride!

When it comes to vintage Seiko chronographs, most gatherers center intensely around either the 6138 or 6139 pieces. These were the huge sprinters that commenced everything for Seiko. All things considered, it was the 6139 that shown up on the scene in 1969 close by the other programmed chronograph pioneers. Notwithstanding, there’s more to life than these phenomenal pieces. Like the three-gave watches, incidentally, Seiko’s Daini (second) manufacturing plant was up to its standard tricks. This implied that they were competing with the Suwa processing plant (the home of those 6138 and 6139 pieces) and making some exceptionally inventive watches. I just so end up reasoning that the Seiko 7015-6010 Time Sonar turns out to be one of the best.

The Seiko 7015-6010 Time Sonar Chronograph

What you see before you today is one of the craziest looking watches I own. This is the Seiko 7015-6010 Time Sonar Chronograph and it asks discussion. Dissimilar to the numerous moderately customary chronographs that poured from the Seiko industrial facilities, the Time Sonar feels like a ’70s style corrosive excursion into a space matured future — Japanese style. What you notice initially is a generally bustling greenish dial with heaps of weak composing that looks a piece “digital”. After looking into it further, however, you’re really seeing both the day and date wheels under the dial. What makes it even more captivating is the way that there are Japanese kanji substituting with English days of the week. It’s this hazy round look that helps one to remember a sonar screen, subsequently the name.

One of the most mind blowing dials I’ve seen

There’s significantly more to the Time Sonar dial beside its extraordinary transparent properties. Seiko capably rehearsed limitation here with some fragile white hour cuts that don’t detract from the green segment. Likewise on the dark external moment ring with white sections and the dark upward slanting tachymeter scale that goes about as a tensioner ring. The plan work proceeds at both 3 and 9 o’clock where dark fragments run the distance across of the dial. It’s here that we see marking, the model name, day/date window, and some pusher guidelines similar as a cutting edge G-Shock. White hands with “floating” dark focuses and a splendid orange chronograph hand coordinates a comparing triangle at 12:00. Simply take this watch in briefly, consider all the subtleties, and inquire as to whether you could make a superior showing of composing a particularly epic last product.

The modern dial on the Time Sonar surely looks like it and, fortunately, the Daini people kept speed on the remainder of the watch. A level mineral glass finishes things off and is encircled by a calculated and cleaned bezel. This bezel stands out consummately from the dab shot top of the case. I’m by and large no enthusiast of lugless plans, yet this 39mm steel case fits the character of this watch so well because of its distinct effortlessness. The case looks extraordinary with its cleaned flanks, however it’s absolutely not the superstar here. Similarly, I appreciate the flush crown and basic cleaned round pushers that stretch out from the case.

A totally different sort of movement

Since the Time Sonar is a chronograph, you’ve without a doubt saw that it needs sub-registers. This watch is a basic brief counter, yet it’s not that basic. The upper pusher starts and stops the development while the lower pusher restores the hand to 12:00. In any case, there’s more since this is a flyback development and that implies that it very well may be reset while running. It’s a flawless element on this 21-gem cam worked 7015 type programmed. This development doesn’t take into consideration hand twisting, yet the crown offers day changes with a push and date changes by hauling it out to the first position.

And a touch of show and tell

If you’re getting a charge out of the ride up until now, the Seiko Time Sonar has one more stunt at its disposal. Flipping the watch over uncovers a smoky screw in the event that back. In what probably been one hell of an amazement during the mid-’70s, this is the principal Seiko chronograph with a showcase back. Seiko utilized a type of plastic for the showcase and printed the model number and sequential on this material. Consequently, most chronic numbers (counting mine) are presently a distant memory. You can see the development and its dark covered rotor. In my view, it’s subtleties like the case back and rotor that make this watch a particularly extraordinary piece in an ocean of different chronographs from the era.

The bracelet

The Time Sonar transported several distinct wristbands. The notable “fish bone” was near and this 19mm “Jubilee” style that you see here. It’s really one of the better wristbands from Seiko and coexists well with my wrist hair. The fasten highlights miniature change pin openings and connection expulsion is accomplished by sliding out little snares that associate the little community joins. Indeed, I imagine that Seiko picked the plan well to coordinate, yet not overwhelm, the dial.

A contact of history

The Seiko Time Sonar appeared at some point in the principal half of the 1970s and was made for quite a long while. I’ve done a lot of looking and can’t appear to discover precise dates. There were a few variations including a 7015-6010 model with a hazy earthy colored dial and an out and out various 7018-6000 with dark dial and sub-register to name only a few. A period just 2260-0690 reference existed with a presentation back too. The Time Sonar I’ve expounded on is generally hard to come by and alluring to Seiko authorities. The developments can be somewhat interesting to support as these were for the most part JDM pieces and not as predominant. Moreover, I’ve seen a few models with broke case backs. Qualities are all finished yet can make a beeline for the $1,000 mark at times.

The vintage Seiko Time Sonar 7015-6010 is perhaps the most special watches in my assortment. It’s totally unique in relation to anything Seiko was making at that point and they’ve never really like it since (in spite of the fact that Dave requested its return in a new article ). On top, all things considered, they ended up making an enchanting looking watch indeed.
