The MWC 100m/330ft water-resistant G10 models in stainless steel are among our longest-established G10/GS series watches, with variants used by the military since the mid-1980s. This version, identical to the NATO variant, has been supplied to a Search and Rescue (SAR) unit in Canada, hence the high-visibility orange strap. This updated model has been allocated the NATO Stock Number NSN: 6645-99-472-3228 by the Ministry of Defence Codification Agency, marking it as the most current approved specification. Please see the attached image for the MOD codification sheet.

This watch features a highly scratch-resistant sapphire crystal and boasts an impressive 10-year battery life. Although this G10/GS specification watch traces its origins to our earliest G10 designs from the 1980s, it is thoroughly updated.

The screw-down crown and screw caseback significantly enhance water resistance, while the Swiss Ronda 715li movement with a 10-year battery life greatly reduces maintenance needs. The case has a light sandblasted, non-reflective finish, a process long used by military watch manufacturers to give the case a matte appearance that minimizes light reflection. This finish is achieved by blasting the watch case with tiny glass or sand particles, hence the term sandblasted.

The contract specifications for this model required it to be covert, with a screw caseback, 100m water resistance, sapphire crystal, and screw-down crown, resulting in a low-maintenance and highly durable timepiece. The watch is supplied with both a high-visibility orange SAR strap and a gray 20mm heat-welded NATO strap in Admiralty Grey.

The back of the case bears various contract markings, including the unique serial number.

Benefits of Sapphire Crystal:

Many people ask about the benefits of sapphire crystal over standard mineral crystal. Synthetic sapphire is the best material for watch crystals due to its strength and shatter and scratch resistance, making it highly appealing to military personnel, security personnel, police officers, and those with active outdoor lifestyles. These groups make up over 70% of our customers. When accidents occur, over 90% of watches with cracked crystals have mineral glass crystals. Even hardened mineral crystals do not match sapphire for durability under adverse conditions.

Sapphire crystals are heat-treated to remove internal stresses, enhancing their strength. Additionally, they receive two layers of anti-reflective coating. Sapphire crystal's robustness is why it's now used on the latest iPhones. However, due to its cost, sapphire crystal is typically found only on higher-end watches.

Great Long-Lasting Replacement Heads for BURST Toothbrush
Color: Rose Gold, Color: Rose Gold
I really like these replacement toothbrush heads for my BURST electric toothbrush. They seem to last a very long time compared to many other toothbrush heads I have tried. The bristles hold up really well and do not get worn down or frayed quickly, even with regular use. While I still try to replace my toothbrush heads routinely for hygiene purposes, I honestly feel like these could easily last for several months if needed. The replacement heads attach perfectly to the toothbrush and feel very secure once connected. I also appreciated that they offer them in pink because it matches my toothbrush perfectly and adds a fun touch. The price also feels pretty reasonable for a three-pack considering the quality and durability of the heads themselves. My only small complaint is that they are made of plastic, which I personally do not love from an environmental standpoint. I also am still undecided about the black bristles because it can make it harder to tell if the toothbrush is fully clean after use. Other than that, the product arrived exactly as described and pictured, and overall I think these are excellent replacement heads for anyone using a BURST toothbrush.

The best electric toothbrush ever
Color: Rose Gold
Dentists on the tube agree, this is the best clean you can get and at such a low price compared to the others. These heads are durable, they last me like 4 months each, maybe more. Functions great with the vibration levels of the burst and unbeatable battery life.
