Heuer Solunar Ref 279.603 Tropical Dial


We are offering this very rare and unusual Solunar by Heuer.

The Solunar theory comes from the work of John Knight who devised a system based on the sun (SOlar) and the moon (LUNAR) for tracking the activity of animals for hunting and fishing .
The super cool black and silver bezel shows the tide position and the rotating internal bezel has a two week reading allowing the monitoring of tidal patterns of a fortnight.

The 45mm steel case is in excellent condition and the metallic blue dial has turned tropical to a chocolate hue and has day and date readings at three o’clock. The watch will come on the pictured leather strap with a steel Heuer buckle fitted. The ETA movement has been fully checked and regulated by our watchmaker.

It's not all about famous models at Bulang and Sons.
We really love finding interesting off the beaten track pieces like this too. We’d love to help you find exactly what you’re looking for, so please get in touch!

Our Service

Each vintage timepiece is individually selected and carefully inspected by our team of experts. After we buy a watch it is mechanically inspected and fully checked by our watchmaker. If necessary, the movement will be fully serviced and tested to ensure it is running to our exacting standards.

We will always describe the watch as fully as we can in our sales texts. Our zoomable images are of the highest possible quality and form an important part of each watch’s description. We will never hide or cover up any element of any watch we sell.

Key to our unparalleled service is Fedex Priority shipping, fully insured. Once you have received your watch, we encourage you to inspect it thoroughly. If you are not 100% satisfied, please let us know. We offer a 14 days return policy. Simply return the watch to get a full refund of the original purchase price.

Our Warranty

We offer a one-year warranty on the mechanical function of the watch, starting from the day of purchase. We do not guarantee the waterproof nature of any (vintage) watch, unless expressly made in writing. Therefore, our warranty will not cover any damage done to the case and/or movement by water or moisture entering the watch. Our warranty does not apply to accidental damage or mishandling of your watch and does not extend to the bracelet, case parts (including pushers, winding stem, crown and bezel), watch glass, dial and hands.
