At this price point, you'll primarily find quartz movements. Quartz watches are battery-powered and known for their accuracy and reliability. While mechanical or automatic movements are highly prized in the watch world, they are rarely found (and often unreliable) in the under $30 category.

Case materials typically include plastic, resin, or alloy. While these materials aren't as luxurious as stainless steel or titanium, they can still be durable and offer resistance to scratches and minor impacts. Pay attention to the quality of the material and the overall construction.

Common strap materials include silicone, nylon (NATO), or faux leather. Silicone straps are comfortable, water-resistant, and easy to clean, making them ideal for sports and outdoor activities. Nylon straps are durable and offer a variety of colors and patterns. Faux leather can mimic the look of genuine leather but may not be as durable.

While you shouldn't expect deep-sea diving capabilities, look for watches with a water resistance rating of at least 3 ATM (30 meters). This level of water resistance should protect the watch from splashes, rain, and brief immersion in water. Avoid wearing watches with lower water resistance in situations where they might get wet.

A watch is useless if you can't read the time easily. Look for clear dials with contrasting colors and legible numerals or markers. Consider the size and style of the hands as well. Some watches may feature luminous hands or markers for better visibility in low-light conditions.

Don't expect a plethora of features at this price point. Focus on the essentials, such as time, date, and potentially a chronograph (stopwatch) function. Avoid watches with overly complicated features that may be prone to failure.

Online marketplaces like Amazon, eBay, and AliExpress offer a vast selection of watches under $30. Be sure to read customer reviews and check seller ratings before making a purchase. Look for reputable sellers with a history of positive feedback.

Discount department stores often carry a selection of affordable watches from various brands. These stores can be a good option for finding watches in person and trying them on before you buy.

Even established online watch retailers sometimes have clearance sections where you can find discounted watches that fall within your budget. Sign up for their email lists to receive notifications about sales and promotions.

Digital watches offer clear time displays, often with additional features like alarms, timers, and stopwatches. Brands like Casio are known for their durable and affordable digital watches.

Analog watches feature traditional hour, minute, and second hands. They offer a classic and timeless aesthetic. Look for simple and elegant designs that are easy to read.

Sports watches are designed for active lifestyles and typically feature water resistance, durable materials, and chronograph functions. Brands like Timex and Armitron offer affordable sports watches.

Fashion watches prioritize aesthetics and design over functionality. They come in a variety of styles, from minimalist to bold and eye-catching. While durability may not be the primary focus, they can still be a great way to add a touch of style to your outfit.

Quartz watches require battery replacements. You can usually replace the battery yourself with a small screwdriver and a replacement battery, or you can take it to a jeweler.

Clean your watch regularly with a soft, damp cloth to remove dirt and grime. Avoid using harsh chemicals or abrasive cleaners, as they can damage the finish.

Store your watch in a dry place when you're not wearing it. Avoid exposing it to extreme temperatures or humidity.

Even if your watch is water-resistant, avoid prolonged exposure to water, especially hot water or soapy water.
