Beautiful watches, very suitable for everyday use. Robust and interesting price. Already have 4 watches in my possession and enjoy them every day!

Thorsten W.

The watch was delivered quickly. It exceeds all my expectations in quality and precision. A true gem! The accuracy has settled in the course of a week after initial +5 sec to +1 to +-0 and runs since 4 days stable in this range.

Automatic watch Sea Ground G100 Vintage - Made in Germany:

  • Quality Made in Germany: all watches of the SEA GROUND 100 collection bear the quality seal Made in Germany and are manufactured by our watchmakers at our headquarters in Würzburg. Only after an extensive quality control including water resistance test and rate test the watches leave our house.

  • Automatic movement, caliber Seiko NH35: the robust quality movement NH35 from Seiko Instruments performs reliably in our diving watch. Despite its standard high accuracy, each individual movement is finely regulated by our watchmakers. The movement has an automatic winding in both directions, a power reserve of more than 41 hours, a second stop and 24 jewels.

  • Double anti-reflective sapphire crystal with anti-reflective coating: a sapphire crystal, unlike a plastic or mineral crystal, can withstand extreme stress. With a hardness level of 9, just like the natural gemstone sapphire, only diamond can boast an even higher hardness level. Therefore, the sapphire crystal is ideal to protect the watch glass from unsightly scratches. To achieve high readability, the sapphire crystal has been double anti-reflective coated with a blue anti-reflective coating.

  • Swiss Super-LumiNova: the indexes and hands of the SEA GROUND 100 are equipped with SWISS SUPER-LUMINOVA luminous material in the "Old Radium" version from the Swiss company RC TRITECT AG. The highest quality luminous material on the market guarantees high luminosity for many hours.

  • Elegant calfskin strap: The handmade calfskin strap gives the watch a certain exclusivity and guarantees the highest wearing comfort.

  • 100m/10bar water resistant: the SEA GROUND 100 is a vintage diver's watch. And this is exactly what it was designed for. Due to the complex case construction as well as the screw-down crown and the screw-down, solid case back, we can guarantee a water resistance of 100m/10bar.

A coincidence? the story



For more than 30 years, everything for the founders Christian Schmitt and Hans Meeder has revolved around their passion WATCH. As chance would have it, Hans Meeder got his hands on a gift from his uncle from 1976, complete with the original invoice, at just the right time: it was a beautiful Gigandet sports watch with the design typical of the 1970s. The discovery did not let Hans Meeder go. Subsequent research revealed that Gigandet watches had disappeared from the market. Her intuition for brands and her passion for timepieces, together with her experience in technology and sales, led her to the decision to revive the Gigandet brand. Her mission: to develop quality watches with character away from the masses - authentic lifestyle included.

The history of Gigandet

The company Charles Gigandet S.A. was founded in Switzerland after the 2nd World War. The distribution of the watches was successful mainly in the USA and Europe. Around 1970/80 the market for mechanical watches collapsed, due to the successful introduction of high quality quartz watches as well. As a result, Gigandet had to stop production and the company was abandoned...

The discovery did not let Hans Meeder go. Subsequent research revealed that Gigandet watches had disappeared from the market.

Our vision is our drive

Our vision is to continue the legacy and philosophy of CHARLES GIGANDET. We see this as a personal responsibility, this encourages us to go this way. Our long experience for timepieces, together with the enthusiasm for craftsmanship, led us to the decision to revive the brand GIGANDET.

Uncompromising quality - Made in Germany

From the warehouse to the watchmaker, service, development, marketing, design, and technical development, everything is implemented at the Würzburg site. As a result, everything meshes like individual cogs in a clockwork mechanism.

Traditional craftsmanship combined with the highest precision - this ensures high reliability and longevity of our watches.

No GIGANDET watch leaves our manufactory without the loving handwork and the scrutinizing eyes of our master watchmakers, as well as a detailed and final quality control.

We perform almost all types of repairs and tests on GIGANDET automatic watches in our master watchmaker workshop.

As long as a watch runs smoothly, we generally advise against a hasty revision. At the earliest from the fourth year after purchase, we recommend to think about a revision. Should you decide to do so, we can perform it on any watch purchased from us and thus guarantee a long shelf life.

You have an older model of our watches and would like to have it modernized to our latest standards? That's no problem. For example, we can replace the aluminum bezel with a ceramic bezel on select models in the G300 series. On our G2 models, the mineral crystal can be replaced with a scratch-resistant sapphire crystal. If you are interested, just contact us by phone, mail or fax.

Frequently asked questions

Can the time setting ring only be rotated in one direction?

Yes.
The bezel is only unidirectionally rotatable. More precisely, it can only be turned to the left.

Can I just change the straps on your watches by myself?

Yes.
For our stainless steel bracelets, all you need is a small screwdriver to push the spring bar together at the case band joint and remove the bracelet
If you want to have a leather strap on your watch, you can install one of our many original leather straps with an easy-release function without any tools at all.

Can the watch also be wound by hand?

Yes.
To do this, you must loosen the screw connection. You can then wind the watch clockwise by hand. Afterwards, however, you should be sure to screw the crown back in correctly so that the water resistance is guaranteed.

Can I have individual adjustments on the watch with you?

Yes.
We can make almost any modification request as long as it is technically feasible. You would like to have a different dial, bezel or bracelet than the one provided for your model? Feel free to contact us by mail or phone.
