This is Stan Czubernat's 3rd book in his "Trench Watches of the Great War" series.


341 pages will document that Charles Leon Depollier truly created the world's first waterproof wrist watch with 

the 1918 Waltham Depollier "Field & Marine" Waterproof  Watch followed closely by the 1919 Waltham Depollier

 "THERMO" Waterproof Watch. The 4 different waterproof crown designs developed in the house of Depollier

 during the Great War years will be covered in detail. Evidence included is the complete trial transcript of the

 1919 lawsuit between Charles Depollier vs Mortimer Golden. This is Charles Depollier's fascinating first hand

 account of how he developed waterproof wrist watch technology 8 years before Rolex in cooperation with

 high ranking officers of the United States Army Signal Corps Engineering & Research Division. 

Depollier's waterproof wrist watch case was independently tested in Washington D.C. by the United States 

National Bureau of Standards for its waterproof ability, it passed their tests with flying colors. All paper 

lawsuit exhibits from both parties are included, every page. Two official United States War Department 

reports corroborate Depollier's sworn court testimony. In one of these reports Two Star Major General George

 Squier informs the United States Secretary of War , Mr. Newton Baker, that the "watch could actually run for

several weeks under water".  Mr. Baker reported directly to President Woodrow Wilson. You will also read the

 correspondence of high ranking. U.S. Army officers discussing Depollier's waterproof wrist watch technology and

 how it would solve many of their problems in 1918. Also included are the Waltham Depollier trench watch

 advertisements and the non-waterproof Waltham Depollier military watches produced during the Great War era.

For years the writers in the watch industry, watch magazines, the most renowned auction houses in the world,

 major newspapers and online watch media outlets have been giving you incorrect information about the true

 origins of waterproof wrist watch technology. They could not have gotten this story more wrong by saying Rolex

 was the one who developed this technology in 1926 with the Oyster. Military records have always been considered

 the "holy grail" of documentation, the benchmark of evidence. There is simply no way to put a spin on the date

 stamped military documents I've discovered in the United States National Archives. How can Rolex possibly

 account for Depollier's watch being successfully independently tested for waterproof ability, approved and

 purchased by the U.S. government 8 YEARS before they released the Oyster? They can't. My allegiance is to

 horological history and giving credit to the individuals who actually changed the industry, not to perpetuating

inaccurate myths.
