Comparison Suunto Race S vs Suunto Race

The size of the display installed in the gadget; for round screens, respectively, the diameter is indicated.

A larger screen, on the one hand, is more convenient to use, on the other hand, it significantly affects the dimensions of the entire device, which is especially critical for wearable gadgets. Therefore, manufacturers choose the display size in accordance with the purpose and functionality of each specific model — so that there is enough space on the screen and the device itself is not too bulky.

It is also worth mentioning that screens with a similar size may have different aspect ratios. For example, traditional smartwatches are usually equipped with square or round panels, while in fitness trackers, screens are often made elongated in height.

The density of dots on the screen of the gadget, namely, the number of pixels that are on each inch of the panel vertically or horizontally.

The higher the PPI, the higher the detail of the screen, the clearer and smoother the image is. On the other hand, this indicator affects the price accordingly. Therefore, the higher the density of points, the more advanced, usually, this gadget is in terms of general capabilities. However, when choosing a screen, manufacturers take into account the general purpose and functionality of the device; so that even a small number of PPIs usually does not interfere with comfortable use.

The material from which the transparent cover of the display is made.

— Plastic. Inexpensive, moreover, quite durable and impact-resistant material: even with a strong impact, the plastic is more likely to crack than crumble into fragments. At the same time, scratches easily appear on such a surface, and over time it inevitably becomes cloudy. Because of this, plastic is found predominantly in inexpensive wearable gadgets.

— Glass. In this case, it can mean both classic silicate glass (the same as, for example, in windows), and some original types of impact-resistant glass that are not related to Gorilla Glass(see below). Regular glass costs more than plastic, but not by much, and it looks better and stays clear longer due to its scratch resistance. The main disadvantages of this material are fragility and a tendency to crumble into sharp fragments upon impact. Impact-resistant glass types are devoid of this drawback to one degree or another, but they are also more expensive. According to the price category of the gadget, you can quite accurately determine what kind of glass it uses — ordinary or shock-resistant.

— Sapphire. The coating made of synthetic sapphire is used exclusively in premium-class gadgets — this is due to the complexity of its production and, accordingly, the high cost. On the practical s...ide, sapphire is extremely scratch resistant (it is only possible to scratch such glass with a diamond or special tools), but at the same time it is fragile and easily breaks from impact.

— Gorilla glass. A family of shock-resistant glass types created by Corning and widely used in modern electronics, including wearable gadgets. In addition to strength, Gorilla Glass is also distinguished by good scratch resistance, while being relatively inexpensive (by the standards of such a coating), which has led to their popularity. However, the specific properties of such glass depend on its version; Here are the options that are relevant for modern wearable devices:

• Gorilla Glass v3. The oldest current version was released in 2013. Nevertheless, even such a coating is noticeably superior to traditional glass (not to mention plastic) in terms of transparency and scratch resistance.
• Gorilla Glass v4. Version released in 2014. A key feature was that the development of this coating focused on impact resistance (whereas previous generations focused mainly on scratch resistance). As a result, the glass turned out to be twice as strong as in version 3, despite the fact that its thickness was only 0.4 mm.
• Gorilla Glass SR+. The first version of Gorilla Glass, designed specifically for smartwatches and other miniature wearable gadgets; presented in 2016. According to the creators, the scratch resistance of such coatings approaches those of sapphire glass while maintaining the main advantages of Gorilla Glass — high strength and transparency. In general, for this material, superiority over "alternative options" is claimed by 70% in terms of strength specs and by 25% in terms of optical properties.
• Gorilla Glass DX. Another type of glass, specially designed for wearable devices. It was released in 2018 at the same time as the DX+ version (see below). Of the key improvements in Gorilla Glass DX, in particular, increased anti-reflective properties and an increase in the contrast level of the visible image by 50% are announced; the latter, among other things, allows you to reduce the actual brightness and, accordingly, the power consumption of screens without compromising image quality, which is especially important for miniature wearable devices. And this material differs from the DX+ type coating, on the one hand, by lower scratch resistance, and, on the other hand, by higher anti-reflective specs.
• Gorilla Glass DX+. Almost the same as the original version of DX, related to the same specialization — wearable wearable gadgets and other miniature devices. At the same time, DX + has a higher scratch resistance, but has slightly worse anti-reflective specs. Otherwise, these types of coverage are almost identical.

The amount of own storage provided in the design of the watch/bracelet. This memory is used for permanent storage of various information: call log, received SMS and other messages, additional applications, data on physical activity for a certain time, etc. The larger its volume, the more data can be stored in the device without the need to clean it to free up space. On the other hand, in the operation of smartwatches, large volumes ( 64 GB, 32 GB, 16 GB, even 8 GB and 4 GB) are not always required, capacious drives are quite expensive, and replaceable cards installed in corresponding slot (see below).

The time that the gadget can work on one battery charge (or the supplied battery) in normal use.

Normal mode, as a rule, means working with a relatively low load. At this time, the display can display some data, and basic functions can also work (counting steps, periodically checking heart rate, etc.), but in any case, power consumption is low. Therefore, the operating time in normal mode can be quite impressive, up to several weeks, or even months. However, when choosing, it doesn’t hurt to also pay attention to the stated time in active mode (see below) — especially if a long operating time is critical, or you plan to use the gadget intensively. The actual autonomy of the device will most likely be somewhere in between these two values, depending on the actual load. If only the time in normal mode is indicated for the gadget, you should choose with a certain reserve.

The time that the gadget is able to work on one charge of the battery (or supplied battery) when using a GPS sensor.

This parameter is specified mainly for high-end tourist watches designed for experienced travelers, military, rescuers, divers, pilots, etc. Such devices use advanced GPS receivers, which themselves can consume quite a significant amount of energy; in addition, the operation of the receiver is inevitably accompanied by the use of other features — transferring navigation data to another device (usually via Bluetooth), working with its own built-in maps, etc. Therefore, the battery life while using GPS turns out to be rather modest — it can be significantly less time in active and even less in normal mode (for both, see above).

We also remind that the battery life mentioned in specs is approximate — in fact it may differ (in one direction or another, depending on the use scenario). Nevertheless, it is quite possible to evaluate the actual capabilities of the watch and compare them with each other: the difference in the claimed battery life usually proportionally corresponds to the difference in practical battery life.

Wrist coverage suitable for the included watch strap. Usually, the length of the strap can be adjusted, so this paragraph usually indicates not one number, but a range — for example, "130 – 200" (millimetres). If there are several straps in the kit, then several ranges are indicated in the specs, if necessary, with a clarification like “fabric: 115 – 185, metal: 130 – 220” (if the straps are made of different materials).

We emphasize that in this case we are talking not just about the length of the strap, but about the girth of the wrist, for which it is designed. Thus, by measuring your hand in an appropriate way, you can accurately determine whether a particular strap is suitable for a particular person or not. This possibility is especially important if the watch is bought for a user with a non-standard hand size — miniature or, conversely, very large.

The level of dust and water protection according to the IP standard, which the gadget corresponds to.

This parameter is usually denoted by the letters IP followed by two characters ( IP55, IP56, IP57, IP65, IP66, IP67, IP68, IP69) — for example, IP68. The numbers indicate the specific degree of protection: the first — dust resistance, the second — water resistance. Instead of one of the numbers, there may be the letter X ( IPX5, IPX7, IPX8) — this means there is no certification for this indicator: for example, an IPX7 device has a moisture resistance of 7, but has not been tested for dust protection. However, a high degree of protection against water automatically means good dust resistance.

Here are the levels of dust protection (first digit) found in modern wearable gadgets:

5 — dust resistance. Some dust may get inside, but it does not affect the operation of the device. There is no point in specifying lower levels, as they do not provide protection against dust.
6 — full dustproof (dust ingress is completely excluded).

The second digit describes the r...esistance to moisture, here the options can be as follows:

4 — resistance to water splashes from any direction. It is considered the minimum level of water protection, which makes sense to indicate in the specs: in particular, it allows you to endure exposure to rain without consequences.
5 — resistance to water jets from any direction. This level allows you to endure heavy rain and makes it possible to at least calmly wash your hands without removing the gadget.
6 — protection against strong water jets and impacts of sea waves. It is undesirable to completely submerge such a gadget under water, but it can be used even in a strong storm and not removed during the shower.
7 — the possibility of short-term immersion under water to a shallow depth (up to 1 m), without constant operation in immersed mode. With such a device, usually, you can even swim — but for a very short time (several minutes) and without diving. However, it is worth noting that not every gadget with this level of protection normally tolerates water jets (that is, compliance with level 7 does not necessarily mean compliance with lower levels 5 and 6).
8 — the possibility of a long (more than 30 minutes) stay under water at a great depth (more than 1 m), using in submerged mode. The specific limit of depth and time may be different, it should be specified separately; there are both gadgets with basic capabilities that allow you to dive a couple of metres, and diving models with an allowable depth of several tens of metres. Similar to level 7, water jet resistance is not guaranteed in this case.
9 - the possibility of almost unlimited time spent under water when diving to a certain depth, using the device in submerged mode. Level 9 also guarantees resistance to hot water under strong pressure - wrist gadgets with this level of dust and moisture protection can withstand high-temperature water jets under pressure.
