Bronze Torsk-Diver with Harbor Grey Dial by Tsao Watches


Introducing the Limited Edition Bronze Harbor Grey TORSK-DIVER.

With a limited quantity of 423 pieces in marine grade CuSn8 bronze case, each timepiece will be individually numbered as No. xxx / 423 (to pay homage to the SS-423 submarine, also known as the USS-Torsk).

The TORSK-DIVER is named after the USS Torsk submarine, currently located in the Baltimore Inner Harbor.  The USS Torsk was one of ten Tench-class submarines to see service during World War II and happened to sink the last enemy ship in 1945.  It has since been decommissioned and is currently being used as a museum ship, managed by the Historic Ships in Baltimore. 


The automatic Miyota 9015 by Citizen was our number one choice for the TORSK-DIVER. Many reviews have compared it to the Swiss ETA movements in terms of timekeeping and performance without the high price tag. Having used it for our first model, we were extremely pleased with the accuracy and reliability.  As an improvement to an already incredible movement, we will also regulate the movement in 4 positions.

The 9015 includes a date window, 48 hour power reserve, and beats at 28,800 VPH (Vibrations Per Hour), resulting in a very smooth sweep of the second hand. It is also shock resistant and includes a hacking function, making it one of the best values on the market. Best of all – no battery needed.

Case Material:

The Marine Grade Bronze TORSK is corrosion resistant and forms a natural oxide layer over time.  This extra layer, called patina, protects the metal and gives a unique design – initially the timepiece will have a rose gold tint that will darken to an artisan brown.
