For those unfamiliar to the topic: Bulova in the beginning (1917-1919) was largely a purchase activity. They purchased movements in Switzerland (plus some cases) and purchased their cases in the USA (until they started making their own cases in 1920). They decided to buy the case for this 13 ligne movement in Switzerland and not in the USA.

Nonsense Alex. 

'In 1912 the company opened its first plant in Biel, Switzerland, dedicated to standardized mass production of watch components and jeweled movements'

1918 printed on the ad is of interest, it is the only solid date We have as to the Year of production. 

The lack of any manufacturer name on the movement in the ad raises more questions than answers, imo

A small details here is running in my head.  is it possible bulova have made a military non issue after ww1 to sell their overstock as those from ww2 with a different back case ??? 

I explain myself... on ww2 non issue watch they are a standard serial number. And on military issue we see the numerous marking for the army / war.

The subject watch here have a #2 serial number inside back case BUT me and Fifthavenue hold 2 of these watch and they dont have this "serial #" 

interesting fact the circle marking inside the back case of my watch and the Fifth watch seem very deeper than the subject watch..... maybe just an other batch but ....

My watch do the war and the owner have his name engraved at the back. The grand daughter of the original owner of mine have confirmed this. i know it maybe just a story but the guy is in ww1 files.  

So much mystery about these ww1 watch. Will wait for more exemple and maybe some info on these beauty !

Bulova did not sell watches to the US military in WW1, given they were a small start up and not considered. The US military (government) had contracts with large domestic suppliers such as Elgin and the likes. Only by WW2, Bulova had become a large and established company that got the military government contracts to supply watches.

Thank Alex ! You are right about Bulova was a 2 years startup at the begining of ww1 (1914).

 To complete your ad of 1918  i noticed this jeweler ad ,from 1918 too, posted by Admin in the part advert from the 10s. The ad say : "the same type used at the front". 

So that let only one choice : These 3 rubaiyat trench watch have been bought at the end of the war in 1918/+ and they are all non-military issue.(trench watch "STYLE / TYPE" only) But made by Bulova with the Rubaiyat name. 

This theory can crash if we find an advert of these rubaiyat trench watch dated before 1918..... if so, some soldier could have fight in ww1 with one of these on the wirst.... but chance are very light and i know it now....

Mine was probably purchased by a soldier on the way back home as a souvenir watch and he pay to engrave his name on it to celebrate his return on his feet...... Cool thing so far for Leo. Harper. ( Name engraved at the back of mine )

So by these two adverts, i assume 1918 will be more accurate now for these 3 trench watches.

Thank again Alex to bring me back on track !

I could not disagree more. 

U.S. forces were not the only Military fighting in WW1.

Being that Bulova was manufacturing in Bienne Switzerland at the time it is more likely than not that these trench watches were worn by European troops.
