For sale we have a 1915 WW1 period Hardy Bros LTD, of Australia, Longines silver trench watch. It has a perfect, white enamel dial with Arabic numerals and Hardy Bros LTD, Sydney & Brisbane signing. It has a 35mm case, with coin edge bezel and coin edge screw back. To the rear is a period initial engraving. It also has Longines patented flexible lugs which add to its already large presence. It has a Swiss hallmarked case for 0.935 silver, with the serial number dating it to 1915. Inside it has a Longines calibre 13.34, with 18 jewels, making it the highest-grade variation.


The dial is white enamel and is in outstanding condition. It is a crisp white tone, with a railroad minute track around the exterior. The hour markers are large, stylised, arabic numerals, whilst there is an in-set sub-second dial at 6 O’clock. It has single second, 5 second and arabic 10 second graduations, clearly marked. The dial is signed below 12 “Hardy Bros LTD, Sydney & Brisbane, Made in Switzerland”. The cathedral style hour hand is original and is a bright thermally blued tone. The minute hand appears to be a well-matched replacement, being a darker tone. The sub-second hand is original with Lollipop counterbalance.


The Swiss made case measures 35mm x 35mm, with a lug-to-lug measurement of a whopping 46mm. Early Longines trench watches like this are known for their distinctive swinging lugs, at 12mm in width. The design was registered to Longines in 1907. A tube soldered to the watch case carries a bar, that the lugs (a loop of wire with widened ends), are attached to. This makes the watch a comfortable fit to the wrist, with the lugs angling down with the strap.

The bezel screws on, with a coin edge finish to the outside. To the right is the original silver tone onion style crown, which has aged handsomely. To the rear, there is a screw on back with coin edge finish, matching the bezel and providing a symmetrical case design. It has a personal engraving of the initials TSE, which is well executed. Inside it is signed with the Swiss bear mark for 0.935 silver. The serial number 3,296,707 is engraved to the inside. The case has an even tarnishing across all elements of the silver and has not been polished.


Inside is the Longines calibre 13.34, which was introduced in 1910. It was used in many WW1 period wrist watches. It carries the marking for Baume & Co who were the importer for Longines. This is the highest-grade variation, with a jewel count of 18, with jewelled centre wheel. It is keeping good time to within +30 seconds a day, with a strong amplitude.


Overall, this is a very good original example, with a high-quality design, case and movement. It also has an interesting appeal to the Australian market, with very few watches making the journey to be retailed down under, in the early years of wrist watches.
