Dual Time Zone Tracking

Effortless Adjustment

The P656 features a 12-hour bezel for simplified dual time zone tracking:

  • Offset the bezel by the required hours to track a second time zone.
  • Example: In Paris, align "9 o'clock" on the bezel with the 3-hour marker to track Miami (6 hours behind).

This design maintains the 300m water resistance and classic diver watch aesthetics while enhancing versatility.


Benefits of Sapphire Crystal

Synthetic sapphire is an industry-leading material for watch crystals, offering:

  • Reliability: Ideal for military personnel, law enforcement, and outdoor enthusiasts.
  • Enhanced Strength: Heat-treated sapphire provides superior durability compared to plexiglass or mineral glass.
  • Anti-Reflective Coating: Ensures optimal visibility under all conditions.

The History of MIL-W-46374-G Watches and the P656

The P656 series traces its heritage to the MIL-W-46374F military specification, first issued on October 14, 1991. Further refinements to the specification during the mid-1990s resulted in the Stocker & Yale P650 Navigator, a highly regarded military timepiece developed for demanding operational use. The P656 carries forward many of the principles that made the original P650 such a successful and enduring design, as illustrated in the final image.

    Buddy filled diesel skid steer with automotive gas engine oil. Used this to help.
    We all know that guy who will buy a $65,000 machine and then only service it once a year with the cheapest oil on the shelf from Rural King or some other place with ultra cheap, home branded, questionably quality oil. Yep. That is my good buddy. So I go to the shop a couple weeks back and he is re-filling the skid steer engine with some ultra cheap, totally not to spec, gas engine oil. I question him and he states that it is perfect oil for the machine being 5W-30. I ask him if it meets the SAE ratings for the diesel, he repeats back that yep... it is 5W-30. So I go grab his New Holland book (C232 track skid steer) and look up the oil requirements, then I look at this junk oil, and I try to explain to him the SAE designations on the back of the bottle and the SAE requirements in the book. He looks at me like I have 3 heads and repeats that it is 5W-30, it is totally good. Someone.... kill me please! He has no clue what I am trying to explain. So I couldn't sleep knowing what he is doing, and I ran to Amazon to see if I can at least get zinc to add to the wrong oil and try to help the cam followers and rockers survive this next year. I found this. I ordered a few bottles and had them shipped to his shop, and I explained to him that these need to be dumped in to at least make an attempt in not prematurely wear the engine that likely is worth $20,000 or more! So the real question is, will he actually dump these into the machine, or will he toss them on a shelf never to be seen again? We may never know. But I bet next winter he will once again shop for the cheapest oil on earth to put in a machine that costs as much as some peoples home. He is who he is, you can never change that.

    High quality replacement clips. Highly recommend.
    I used these when replacing the headlight assemblies on my 2011 Honda CR-V. A few clips were already missing before I even started taking the bumper off, and of course a couple more didn’t survive the job. These fit perfectly and snapped right in with no issues. If you’re missing clips or break some while doing a repair, these are a simple fix that gets everything secured again. Very good deal.
