Which models are being compared?
The Casio details below refer primarily to the resin-band MDV-106-1AV listed by Casio Canada. Timex Deepwater includes multiple watches, including 200 m and 300 m models, so claims about one reference should not automatically be applied to the whole collection.

The US-listed MDV106DD-1A1 is a separate metal-band configuration. Casio’s US page displays $99.95 and lists 200 m water resistance, the same 48.5 × 44.2 × 12.1 mm dimensions, and a weight of 145 g. Those details and that displayed price belong to the bracelet variant, not the resin-band MDV-106-1AV. Casio’s US MDV106DD-1A1 listing

Timex Deepwater models
Timex’s collection overview highlights 41 mm cases, ratcheting unidirectional bezels, Super-LumiNova and scratch-resistant sapphire crystals with anti-reflective coating. Treat these as collection-page descriptions and confirm each feature on the exact reference. One concrete example is the Deepwater Reef 200 Titanium Automatic: Timex lists a 41 mm grade 2 titanium case, screw-down crown, screw-on caseback, sapphire crystal, Super-LumiNova, 200 m water resistance and a Miyota 8215 21-jewel Japanese automatic movement.

How do their size, materials and movements differ?
The Duro MDV-106-1AV is larger across the case than the 41 mm size Timex highlights for Deepwater, though the available figures do not establish a complete fit comparison: check the chosen Timex model’s dimensions, including lug-to-lug, before deciding. The Duro’s listed resin band and mineral glass contrast with materials highlighted on some Deepwater references, including sapphire and, on the Titanium Automatic, grade 2 titanium. Confirm the details for the specific model you are considering.

- DURABLE STAINLESS STEEL CASE WITH ROTATING BEZEL: The Casio MDV106 Series features a stainless steel case and screw-down crown, ensuring durability and reliability. The rotating bezel allows for easy time tracking, making it a practical choice for various activities. The sleek analog display with luminous markers enhances visibility.
- 200M WATER RESISTANCE FOR VERSATILE USE: Designed for water resistance up to 200 meters (660 feet), this watch is suitable for daily wear, outdoor activities, and water-related environments. The screw-down caseback and crown provide an extra layer of security, making this a reliable timepiece for various conditions.
- CLEAR ANALOG DISPLAY WITH DATE FUNCTION: The three-hand analog display with hour, minute, and second hands ensures precise timekeeping, while the date display at the 3 o’clock position allows for quick reference. The bold markers and luminous hands enhance readability, making it easy to check the time in various lighting conditions.
- STAINLESS STEEL BAND WITH SECURE CLASP: The stainless steel band with a one-touch 3-fold clasp provides a secure and adjustable fit for all-day comfort. Designed for durability, the stainless steel material offers a polished, stylish look, making it suitable for both casual and professional settings.
The Duro’s quartz movement is the straightforward choice if you value battery-powered timekeeping and the listed approximate battery life. The Deepwater Titanium Automatic’s Miyota 8215 is a mechanical automatic movement; choose it for that style of watch rather than assuming it shares quartz convenience or upkeep.

Casio lists the MDV-106-1AV at 200 m. Timex’s guidance for its 200 m category includes washing hands, light swimming, snorkelling, poolside diving, surfing and recreational scuba diving. This is manufacturer guidance, not evidence of professional dive certification or a guarantee of performance regardless of condition. Follow the manual for the exact watch. Timex also cautions: “To maintain water resistance, do not press any buttons under water unless your watch is indicated as 200m water-resistant.” Timex water-resistance guidance

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which one should you choose?
- Choose the Duro configuration if you want a simple 200 m quartz watch and prefer its listed materials and design. Make sure you distinguish the resin-band MDV-106-1AV from the heavier bracelet MDV106DD-1A1.
- Consider a particular Deepwater if its specific materials, complication or automatic movement matter enough to justify its listed price. Check the reference for water-resistance tier, crystal, movement, case dimensions and band.
- For either watch, compare the exact model reference and intended use rather than assuming that every watch in a collection shares the same specification.
Without comparative hands-on testing and a stated scoring method, there is no evidence-based basis to declare either collection objectively better.
