Design and Performance Enhancements

Built for Modern Demands

Inspired by mid-1990s designs, the P656 watches incorporate significant modern upgrades:

  • Crystal: Shatter-resistant sapphire with anti-reflective coating.
  • Water Resistance: Upgraded from 30m (1990s models) to 300m.
  • Magnetic Resistance: 18.8 Oe for durability in magnetic environments.
  • Shock Resistance: Complies with NIHS 91-10 standards.

Additional Features

  • Screw-down locking crown and caseback for maximum durability.
  • High-visibility numerals on the bezel for ease of use.
  • Optimized dial for readability in low light.
  • Swiss Tritium GTLS for brighter illumination compared to luminous paint.

Covert PVD Finish

The P656 features a matte black, non-reflective PVD (Physical Vapor Deposition) finish, specifically designed for covert operations by special forces, anti-terrorist units, and police forces.

  • Durability: The PVD process chemically bonds the finish to the metal at a molecular level, ensuring superior longevity, even under harsh conditions.
  • Resilience: While extreme abrasion can cause damage, the finish typically lasts for years.

Dual Time Zone Tracking

To meet customer demand for simplified time zone tracking, the P656 replaces the traditional diving bezel with a 12-hour bezel.

Effortless Adjustment

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

This feature maintains the 300m water resistance and classic diver watch aesthetics while increasing versatility.


Benefits of Sapphire Crystal

Synthetic sapphire is the superior choice for watch crystals due to its durability, resistance to scratches, and ability to withstand shattering.

  • Reliability: Ideal for military personnel, police, and outdoor enthusiasts, who represent over 70% of our customer base.
  • Enhanced Strength: Heat-treated sapphire offers unparalleled resilience compared to plexiglass or mineral glass.
  • Anti-Reflective Coating: Ensures clear 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.

    Best place for head
    Size: Queen (Pack of 1), Color: White
    Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

    Oversized
    Size: Queen (Pack of 2), Color: White
    I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

    Amazing - Stop Scrolling and Buy This Pillow
    Size: Queen (Pack of 1), Color: White
    I have been an Amazon customer ever since the very beginning, and this is my first review. Not because I haven’t purchased tons of amazing things (and a few bad ones), just never felt the need. However, I researched pillows for longer than I care to admit, and decided on this one. I’ve had it for about six months and absolutely love it. No lie, I genuinely look forward lying my big head on it after a long day. I am a side sleeper, but flip flop all around through the night and it’s great in every position. Pros: Stays nice and cool, which is soothing regardless of the time of year. Has a sort of quilted textured pattern on the zip up cover, gives it a luxury feel, that breaths nicely even when a pillow case is added. The fill is fully adjustable to your preference. I knew it came with extra filling but was worried it would not be enough. Wrong. It was very full and I ended up taking some out until it was perfect. It comes vacuum sealed and suggests it may take some time to fully take shape. However, I found it to be about 90% almost instantly and was sleeping on it a couple hours later. There was no unpleasant scent sometimes associated with memory foam items. The foam itself is very nice, a mix of what appears to be shredded and cotton candy cloud like. Very brilliant idea, as it is somehow supportive, soft and firm all at once. The affordability of this pillow compared to some of the others in this category can’t be overstated. Oh, and the packaging was very thoughtfully and securely done. If you are like me, an over thinker, I would suggest just taking this for a spin. It’s amazing. I’m not a bot, or working for the company. I’m just truly satisfied, love this pillow, and have been sleeping great.

    It's the perfect pillow!
    Size: Queen (Pack of 1), Color: White
    I purchased this pillow specifically for its customizable fill feature, which allows you to add or remove stuffing to suit your personal comfort needs. Due to the unique curvature of my cervical spine—forward at the neck rather than backward—I require a soft, semi-flat pillow rather than one that is thick or firm. Additionally, I often experience ear discomfort by morning, so a gentler surface is essential. Upon adjusting the fill, I was pleasantly surprised by the generous amount of stuffing included. There was enough to fill an additional pillowcase, and I estimate it could easily create four to five more pillows. The ability to modify the pillow’s firmness at any time is an outstanding feature that makes it adaptable for a wide range of preferences and sleep styles. This pillow has exceeded my expectations in both comfort and versatility. I highly recommend it to anyone seeking a personalized sleep experience.

    Good quality pillows overall
    Size: King (Pack of 2), Color: White
    Got a set of these for my wife and myself as we were struggling with our old pillows. These have some really good qualities and some things we'd like to see changed. First, the good: These are look and feel like they are high quality and made with good materials. The foam itself has a very nice feel to it. We love the fact they are adjustable to add or remove foam. They come with a pretty substantial amount already in the pillow. We appreciate the CertiPur certification. Now the improvements or changes we'd like to see: The foam, while feeling great, doesn't bounce back well if you scrunch your pillows, and so every day you have to fluff and reshape the pillow, moreso than some other memory foam pillows we've owned. One side of the pillow is cooled and you can feel that even through the pillow case, and that's a great thing. However, one side is not cooled and we'd have preferred if both sides were made of the cooling material. Overall, these are good pillows and we are not disappointed with the purchase. They are not, however, our perfect pillows (which do seem hard to find), and at some point in the future will probably make their way to the guest bedroom. We would rate them as some of the better pillows we've tried and feel most people would probably like them.
