17 Jewels Wristwatch
Conoruma - Precision Movement

"Conoruma is Gruen's proprietary alloy used for balance wheels and hairsprings. The Hamilton Watch Company used a famous, similar material called 'Elinvar.' These alloys are designed to be stable in spite of temperature changes—they will expand or contract very little when the watch gets warm or cool. Because a watch is so delicate, changes in temperature will otherwise cause the watch to run slightly fast or slow. Balance and hairspring alloys like Conoruma help combat this problem."

This is a stunning and very elegant timepiece, a vintage Gruen precision wristwatch, "The Precision Watch" dated from 1937. It is a manual wind watch with a Gruen movement, style 289 and caliber 400, 17 jewels, sub second, Swiss made, precision and Conoruma patented.

It has a stunning rectangle case with fancy lugs design, 10K gold filled case and stainless steel back. Glass crystal. It is coming with a vintage Champion 10K gold filled and stainless steel one-piece flex bracelet. Also, this watch is coming in an original Gruen display box.

After 80 years, this watch still looks preserved in time, it still has a perfect white dial with gold Arabic Numerals, bold minute marks and gold matching hands. The dial is signed with the Gruen name and the second hand is located at 6.

Vintage watches are traditionally smaller than today's watches. Men's watches typically measure between 29-36mm (some larger, some smaller) wide excluding the crown. In the listing details we typically try to do our best to list all pertinent dimensions of a watch. If you don't see it, or we failed to do so, please reach out to us. Women's watches from the 1900s-1970s were also somewhat smaller than today’s offerings in many cases. Please also feel free to ask any questions you have pertaining to size.

We prefer to shoot photographs outside when weather is permitting. However, when we shoot indoors, please be aware that we shoot our photographs inside of lightboxes that are lit with 360 LED bulbs. This indeed magnifies any flaws. Usually, they are much less obvious to the naked eye. Having said that, we never photoshop any of our photography, remove blemishes, etc. We adjust light, when necessary, but what you see is what you are getting, and we take pride in that.

The condition is pre-owned.
The item may have some signs of cosmetic wear, but is fully operational and functions as intended.
See all the photos, feel free to ask questions if you have any.

It will be carefully packed.
