MWC "Depthmaster" 100ATM Military Diver Watch

Introducing the MWC "Depthmaster" 100ATM Military Diver Watch, one of our latest and most robust models. This 100% Swiss-made diver's watch is designed to endure extreme conditions, featuring a sapphire crystal and a 100ATM (1,000 meters / 3,280 feet) water resistance rating. It is suitable for diving with mixed gases at extreme depths and includes a wider 24mm strap and a non-scratch ceramic bezel, making it easier to grip in extreme cold. These watches are specifically crafted for professional divers facing very challenging conditions.

Helium Escape Valve

All MWC 100ATM models come equipped with a helium escape valve. This feature addresses the issue of helium molecules entering the watch. Helium molecules are extremely small, allowing them to penetrate the watch seals even when other gases and water cannot. This can occur in saturation diving, where divers spend extended periods at great depths under high pressure.

Helium buildup inside the watch can create internal pressure, potentially causing serious damage or even blowing out the crystal or crown when unscrewed. This is particularly dangerous during time checks or resets. The helium escape valve automatically releases these molecules during decompression, ensuring the watch returns to normal sea level pressure without letting any external elements in.

Importance of Helium in Deep Diving

Helium is crucial for deep-sea diving because it does not cause nitrogen narcosis, unlike nitrogen. Helium replaces nitrogen in most deep-sea mixed gas diving applications. Professional divers working at great depths for extended periods often live in dry environments pressurized with an oxygen/helium mix. Upon surfacing and decompressing, this gas must be safely removed to avoid potentially hazardous situations like the crystal or crown being blown out, which could cause injury.

Benefits of Sapphire Crystal

Synthetic sapphire is the best material for watch crystals due to its exceptional strength and resistance to shattering and scratching. These properties make it highly appealing to military and security personnel, police officers, and individuals with active outdoor lifestyles, accounting for over 70% of our customers. In comparison, over 90% of cracked crystal incidents involve watches with mineral glass crystals. Even hardened mineral crystals cannot match the durability of sapphire under adverse conditions.

Sapphire crystals are heat-treated to remove internal stresses, enhancing their strength. They are made with two layers of anti-reflective coating. Interestingly, sapphire crystal is now also used in the latest iPhone models. While sapphire crystal is more expensive, it is typically found in higher-end watches due to its superior qualities.

    *Some countries are notoriously slow to process goods on arrival, including Israel, Hong Kong, Macau, Mexico, South Africa, and some South American countries. Significant delays can also occur in other countries in Africa. For time-sensitive deliveries, we recommend using UPS, DHL, or FedEx.

    All shipping estimates exclude Saturdays and Sundays.

    While we strive to deliver within the above timeframes, they are guides, and delivery cannot be guaranteed. We are not responsible for delays caused by couriers or any national postal service. If your goods are not delivered within the estimated time, please contact us at admin@mwc.watch, and we will do our best to resolve the issue promptly. We are not liable for any loss caused by late delivery.

    Our delivery charges cover the cost of shipping to you but do not include import charges and administration fees to clear the goods when entering your country if applicable.

    It is the purchaser's responsibility to understand that charges may be levied and to pay all subsequent import taxes and duties on goods shipped to their country. If items are returned to MWC due to rejected payment, subsequent charges incurred (such as import duty and processing costs) will be deducted from any refund issued. For more information, please contact accounts@mwc-distribution.com.

    We do not accept liability for goods lost after delivery to a PO Box. We reserve the right to cancel orders where the delivery address is a PO Box. Similarly, we do not accept liability for goods lost after confirmed delivery to APO or BFPO locations.

    Customer Notification: It is the customer's responsibility to notify us if goods are not received within 21 days of the estimated delivery date. If no notification is made within this period, the buyer is deemed to have received the goods.

    Safe Place Deliveries

    Some delivery companies allow for delivery without a signature, leaving the item in a "safe place" (e.g., shed, garage, porch). If you choose this option, it is at your own risk. We initially send items by a secure service requiring a signature or proof of delivery. Using a "safe place" increases the risk of theft. We advise ensuring deliveries require a signature to ensure safe receipt.

    Failed Deliveries

    If an item is refused and returned to us, we will refund the order less the outbound and inbound shipping charges once the item is received back at our packing and shipping center. For business locations, please notify the receiving personnel of the expected delivery to avoid refusals. Usually, we will be notified of delivery issues and will email you for instructions. It is important to act quickly to avoid return and associated costs.
