Dennison DENCO53 Black



Why We Love It

Dennison made watches for a multitude of explorers and adventurers, probably the most notable of which was Sir Edmund Hilary who said of his Dennison cased Smiths watch: “I carried your watch to the summit. It worked perfectly.”

What You Should Know

These are the only NOS Dennison DENCO53 watches in existence and for sale exclusively within the Alderleigh Collection. Available in black and white but in VERY small numbers.

The UK made 316L stainless steel case is of excellent quality, it has drilled lugs and a Swiss ETA 2824-2 movement. The dial has a superb honeycomb pattern and is reminiscent of so many beautiful watches from the 1950’s and 60’s. The Dauphine hands and 3,6,9 ‘Explorer’ dial all go together perfectly.

A Brief History

The Dennison Watch Case Co. Ltd was established in 1905 by Franklin Dennison and his son Major Gilbert Dennison. It grew to become the most highly respected watch case manufacturer in the world. They manufactured watches for the British Military during The Great War of 1914-18 and parts for military rockets in WWII.

During the 20th Century, Dennison were best known for the cases they made for other watch manufacturers such as Rolex, Tudor, Omega, Longines, IWC, Jaeger-LeCoultre and Zenith. The ‘DW Quality’ was something to be respected.

In 1965, after 115 years of industry and production, sadly The Dennison Watch Case Co. Ltd stopped trading.

In 2015, Dennison attempted to re-launch their cases with Swiss ETA movements but unfortunately the re-launch was unsuccessful. Clearly not through any fault of the watches. Hodinkee agree with us and did a complimentary write up about them here.

Useful Q&A's

No, this Dennison DENCO53 does not come with Papers.
At Oakleigh Watches we endeavour to bring you the best examples of the watches you’re looking for. With very few exemptions this involves ensuring that all key components are original to the watch. On the very rare occasions that any key components have been replaced this will be made clear in the description. All pre-owned watches by Oakleigh Watches are 100% genuine. We do not deal in fakes, replicas or homage watches. For more information, take a look at our blog “Is that the Original?” READ HERE
The watches that we sell are usually pre-owned and therefore pre-worn. The wearing of the watch, even for a short time, is likely to put small marks on the case or bracelet. If any of our watches are pre-worn and unmarked, then it’s highly likely that it has had a light polish at some point. There’s a temptation to think that any polishing is bad, it is not! Check out our blog – “Has this watch been polished?” READ HERE
All our pre-owned luxury watches are tested to ensure that they are water resistant (where applicable) and comply to COSC spec. Passing these tests means they do not require a service at present. If they have recently been serviced, it will be detailed in the description.
Yes, all our pre-owned watches come with an Oakleigh Watches 12-month warranty. If there is an existing warranty remaining from the original watch purpose, it will be stated in the description.
Within 48 hours of cleared payment. 24 hours if possible.
Unfortunately, there is not a straight forward answer to this question, as there are several variables involved when buying a luxury watch for investment. Read our ‘Expert Guide to Buying Investment Watches’ for more advice. CLICK HERE
