The Technomarine Abyss uses silicone oil combined with a quartz movement. If you click on the image to enlarge it you will notice the small air bubble in the oil at the 3 o’clock position.
The Abyss has a case made from stainless steel and uses a mineral crystal and at $600 it represents the most affordable deep dive watch listed.
Unlike the other deep dive watches the Abyss comes with a day of the week indicator, and is also available in blue, black, orange, silver, and yellow.
No longer available on the Technomarine site you can find them at Amazon.
