Is an Apple Watch Right for You?

For iPhone users, the Apple Watch stands out as the premier overall smartwatch. While some smartwatches may cater more specifically to elite athletes, the Apple Watch excels in productivity, safety functionalities, smart home integration, and seamless interoperability with other Apple devices and services. Furthermore, the Apple Watch boasts the most extensive third-party application ecosystem within the smartwatch market.

Wearable devices, by their nature, are intimately personal. The benefits of an Apple Watch are contingent on consistent wear. A costly device left unused detracts from its value. Prioritizing comfort is crucial to ensure regular usage. Before evaluating specific Apple Watch models, determining your optimal size and strap material is a fundamental first step.

SE and Series models are available in two size variants each. The SE is offered in 40mm and 44mm, while Series 7, 8, and 9 are available in 41mm and 45mm. The Series 10 increases sizing to 42mm and 46mm. Larger sizes enhance readability, while smaller sizes may suit users with smaller wrists more comfortably. While both SE and Series watches utilize aluminum casings, the Series 10 also introduces titanium options, in addition to stainless steel available in older models. Aluminum is suitable for most users, but stainless steel or titanium provides enhanced durability for active or accident-prone individuals. Material preference is also subjective, reflecting personal taste in technology. However, be prepared for a price increase for premium materials.

Regarding straps, the nylon sport loop is highly recommended for its breathability, ease of adjustment, and reduced skin irritation compared to silicone alternatives, particularly beneficial for sensitive skin. For more diverse and affordable strap options, online marketplaces such as Amazon or Etsy offer a wide selection. Leather accessories are predominantly sourced from third-party vendors following Apple’s 2023 announcement to discontinue leather production in pursuit of carbon neutrality.

The Ultra and Ultra 2, both 49mm titanium models, feature specialized straps: Trail Loop, Alpine Loop, and Ocean Band. Designed for runners, hikers, and divers, these straps can be chosen based on personal preference. The Trail Loop is favored for its lightweight and versatile design. Ultra straps are compatible with 44mm or 45mm Series watches, and the Ultra itself accepts any 44mm or 45mm Apple Watch strap.

While the Apple Watch is the top smartwatch choice for iPhone users, resources such as fitness tracker buying guides can offer broader comparisons.

Apple Watch Series, SE, or Ultra: Model Breakdown

The Series 10 represents an incremental upgrade, prioritizing user comfort and incorporating a larger, wide-angle OLED display. Upgrading from older models will reveal noticeable improvements in on-wrist visibility. Enhanced speakers improve music and podcast playback, while call clarity benefits from improved voice isolation. The inclusion of depth and water temperature sensors enhances its suitability for water-based activities. Fast charging capabilities have also been significantly improved. In health features, sleep apnea detection, cleared by the FDA, is now included in the Series 10, alongside Series 9 and Ultra 2.

The second-generation Apple Watch SE is recommended for younger demographics and first-time smartwatch purchasers. For existing Apple Watch users seeking an always-on display or advanced health tracking features, the Series 10 is a compelling option. The Ultra 2 is recommended for users requiring the brightest display, maximum durability and extended battery life, and advanced fitness functionalities.

The Series 10 is Apple’s flagship smartwatch, offering the fastest processor, rapid charging, an expanded display, and the latest sensor technology compared to previous iterations. Pricing begins at $399 for the 42mm variant and $429 for the 46mm. LTE connectivity adds $100, excluding carrier service fees. Polished titanium models start at $699.

The second-generation SE features a nylon composite back, contributing to a $30 price reduction from the original model. While offering a cellular option and supporting many advanced features similar to the Series 8, including fall detection, emergency calling, Fitness Plus, Apple Pay, and Family Setup, it lacks an always-on display, EKG, temperature, and SpO2 sensors. The SE also features slightly smaller displays in both sizes. Prices begin at $249 for the 40mm and $279 for the 44mm, with LTE adding $50 plus carrier charges.

For young and healthy individuals, the absence of EKG or SpO2 features in the SE is unlikely to be significant. (Notably, new US-sold watches currently have the SpO2 feature disabled). The SE’s heart rate sensor still provides abnormal heart rate notifications. Apple’s SpO2 functionality is currently limited to spot checks for general wellness purposes, not as a medical-grade replacement for fingertip pulse oximeters.

The EKG sensor primarily serves atrial fibrillation (AFib) detection. For individuals without pre-existing heart conditions, this feature may have limited utility. Major AFib risk factors, according to the American Heart Association, include advanced age, heart conditions, hypertension, family history, sleep apnea, and certain lifestyle choices. If these factors are not relevant, the SE provides a robust health tracking experience with core smart functionalities. Younger, first-time buyers can save significantly by choosing the SE, provided the lack of an always-on display is acceptable.

The Series 10 remains a superior choice for those prioritizing an always-on display or desiring the latest technology. The larger, wide-angle OLED enhances readability, especially for users with visual impairments. It’s also recommended for individuals with heart conditions or elevated AFib risk. Sleep apnea detection requires Series 9, 10, or Ultra 2.

The Ultra 2 currently occupies the premium tier within the Apple Watch lineup. Distinguished visually and significantly larger at 49mm, it features enhanced durability, water resistance, and a raised bezel for display protection. Additional features include a water temperature and depth sensor for diving, triple microphones, dual speakers enabling a Siren function, and a programmable Action button for various functions including workout control and Siren activation.

Starting at $799, the Ultra 2 is the most expensive Apple Watch, with all models including LTE connectivity. Existing Ultra owners considering an upgrade to the second-generation model may find the advancements incremental. Similarly, upgrading to the new black color is also a minor aesthetic change. The Ultra 2 is primarily recommended for new purchasers seeking maximum features.

For users prioritizing battery life, the Ultra models offer the longest performance, achieving up to 60 hours in testing without Low Power Mode. Typical usage including daily GPS tracking or calls may yield approximately two days of battery. Ultras are also ideal for hiking, diving, and trail running. While marketed for extreme exploration, they are practically suited for weekend adventurers and intermediate athletes, or those aspiring to that level.

While no model surpasses the Ultra in battery life, Series 4 and later models can extend battery performance with Low Power Mode, even enabling sleep tracking, though background health sensors are disabled. Series 10 incorporates enhanced fast charging, achieving 0-80% charge in roughly 30 minutes, consistent with testing. Ensure compatible charging accessories are used.

Users with smaller wrists may prefer the Series 10 for its fast charging and long-term wear comfort. Rapid charging becomes particularly useful for quick top-ups before sleep. Series 10 hardware ensures longer-term compatibility with future software features due to its newer processor, making it a suitable upgrade from Series 4 or older models for dedicated Apple Watch users. The SE serves as an entry point, while the Ultra is overkill for average users.

Budget-Friendly Apple Watch Options

The current Watch SE is a recommended option for future-proofing hardware affordably, provided a larger display is not a priority. It offers the same processor as the Series 8 and original Ultra, along with Crash Detection.

While an excellent budget Apple Watch, the second-generation SE is primarily intended as an introductory device, best suited for new Apple Watch users seeking a cost-effective entry point. For users upgrading from older models who prefer not to invest in the Series 10, refurbished Apple Watches offer an alternative.

Purchasing secondhand devices benefits the environment and provides access to premium materials like sapphire glass, stainless steel, or titanium at lower prices. This is also an economical way to upgrade beyond the SE’s features if the Series 10 advancements are not compelling.

Finding the desired model and price may require patience due to limited availability. However, numerous platforms offer older models, often with promotional deals. For secure purchases, verified sources (such as Verge Deals) are recommended. Apple provides its own refurbished models with a full warranty and “like new” condition, although selection can be limited, and prices may not be significantly lower than a new SE. Platforms like Back Market offer condition-based sorting and 12-month warranties.

For refurbished Apple Watch considerations, Series 7 or Series 8 models are recommended for their larger, more readable displays. Use $250 as a benchmark price, aligning with the cost of a new base model Watch SE, with potential adjustments for premium materials. Avoid Series 4 or older refurbished units due to software compatibility limitations and performance issues, despite lower prices.

Apple Watch for Children

For children, a cellular Apple Watch SE or a refurbished cellular Series 4, 5, or 6 is recommended. These models are available in smaller sizes suitable for children’s wrists, and their lower cost provides reassurance against potential damage from active use. Advanced features in watchOS 11 may be unnecessary for younger users. For future-proof options, the second-generation SE and Series 6 are preferable.

Family Setup is recommended for children’s Apple Watches, providing enhanced parental controls. Cellular models supporting at least watchOS 7 are required. Apple’s support documentation confirms compatibility with Series 4 or later and Apple Watch SE for Family Setup.

Family Setup limits certain features, including health data sharing, respiratory rate, irregular heart rhythm notifications, EKG, Cycle Tracking, Sleep, Blood Oxygen, Podcasts, Remote, News, Home, and Shortcuts, while enabling Apple Pay and select health functionalities.

Apple Watch for Senior Relatives

Recommending an Apple Watch for older relatives requires consideration. A cellular Series 9 or 10 is generally advised.

The larger display enhances readability, with adjustable text size beyond the SE and older models. Always-on display improves accessibility, particularly for users with limited arm mobility. Full health features, including irregular heartbeat alerts, walking steadiness, EKGs, fall detection, sleep apnea detection, and emergency calling, are available. Double Tap gesture and improved Siri may also benefit users with dexterity challenges.

While the Ultra is an option, its size and weight may be unsuitable depending on wrist size and health conditions. Series 10 models offer comparable display sizes in a lighter, more comfortable form factor.

Family Setup is not recommended for health-focused use if the senior relative has an iPhone, as irregular heart rhythm notifications, EKG, and health data sharing are unavailable. However, for relatives without iPhones, Family Setup remains a viable option, still providing high and low heart rate notifications, walking steadiness, and fall detection.
