Edox Launches the Neptunian Grande Réserve, a Powerful New Dive Watch

The new Neptunian watch seamlessly blends the functionality of a professional dive watch with an everyday aesthetic.

The name Neptunian should be familiar to dive watch fans and has recently been used by Edox for a genuinely competent instrument, the 1000m water-resistant SkyDiver Neptunian. Following the same design codes but now offered in a more wrist-friendly case, the new Edox Neptunian Grande Réserve combines robustness with daily practicality and a powerful new movement. 

Established in 1884 in Biel, Switzerland, the Edox brand has a rich history. It truly made waves in the 1960s when it wholeheartedly embraced the concept of dive watches. One of its most remarkable creations during this period was the renowned Delfin dive watch, introduced in 1961. This timepiece featured a groundbreaking patented crown system, enabling an astonishing 500-metre depth rating – an unprecedented achievement. Consequently, it rapidly gained popularity among both professional and amateur divers. In 1965, Edox continued to make significant strides with the release of the Hydro-Sub. Then, in 1973, the brand introduced the SkyDiver.

Interestingly, rumours suggest that a special forces colonel commissioned this watch as a covert project. The watch had to meet the demanding requirements of paratroopers in various terrains – whether on land, in the air, or underwater. Over the years, Edox solidified its reputation in the diving world. Today, the brand remains dedicated to crafting rugged timepieces. One of its standout collections, the Neptunian series, draws inspiration and spirit from the SkyDiver line, continuing Edox’s legacy of creating quality watches tailored for adventurers and explorers.

Until recently, The Neptunian collection consisted solely of various iterations of the Automatic model, which the introduction of the new Grande Réserve Date Automatic in stainless steel has now bolstered. These new timepieces come in a 42mm diameter, 12.30mm high case equipped with a unidirectional 60-click rotating bezel featuring a ceramic insert. The 3mm thick sapphire crystal tops the dial, and the overall case construction, including the screw-down crown with a double O’ring system and the solid screw-down stainless steel caseback, ensures the watch is water-resistant up to 300 meters. The caseback is adorned with a Neptune image and relays pertinent information about the watch’s qualities and case number.

The new Neptunian Grande Réserve Date Automatic offers a choice of dial colours, including black, blue, green, and ice blue, paired with black, blue, green, or white ceramic bezel inserts – totalling five new references. On the dial, bold hour indices, prominent hour and minute hands, and the small circle of the lollipop-styled seconds hand are treated with Super-LumiNova X1, ensuring excellent legibility in the dark. A small date window sits at 3 o’clock, balanced by a rectangular hour index at 9.

These new additions to the Neptunian collection are powered by the automatic calibre 808, based on the La Joux-Perret G100. Introduced in 2021, this movement, with dimensions compatible with the ETA 2824, offers 68 hours of power reserve, beats at 28,800vph and is accurate +/-12 seconds per day.

The new Edox Neptunian Grande Réserve is complemented by a three-link stainless steel bracelet with a folding clasp, butterfly-style, featuring a double push-button release. The price is EUR 1,890, and all models are currently available. For further information, please visit

  1. Dear editor…Edox watch workshop is installed at Canton Jura not Biel…thank you

  2. It almost works for me, but I don’t perceive the hour and minute hands as prominent so much as overbearing in the layout of the dial and indices, and therefore detracting and distracting. The design of the hands could’ve provided needed legibility without contrasting so much with the other design elements. But, I’m also aware that I’m obsessed when it comes to the hands of a watch. If the hands don’t fit for me visually it destroys the look for me. The price too is overblown at over $2,000 USD. Different hands and a price point more reasonable, I may be interested. In it’s present configuration, not so much.

    I believe the editor made no mistake saying “established a Biel in 1884”, this is what the Edox corporate site claims. Production was moved to Jura in the 1950s, I trust this is what Alan wanted to be clear about. Nice watch, especially the black-steel-gold version.

Beeindruckt von diesem exquisiten Geschenk überredet sie ihren Mann, in Biel, einer Stadt, die für ihre gut ausgebildeten Uhreningenieure bekannt ist, eine eigene Uhrenmanufaktur zu gründen. Christian Ruefli-Flury nannte seine Firma «Edox», was auf Altgriechisch «Zeitmessung» bedeutet.
