Overview of the kospet m3 smart watch
The kospet m3 is listed by the brand KOSPET as a smart watch in our Smart Watches category, under the product name KOSPET TANK M3 Ultra Smart Watch in silver. The listing gives the model as KOSPET TANK M3 Ultra Smart Watch, so compare that name with your order before you pay on delivery. Keeping the model name in mind will help you match this page to the product you intend to buy.
For daily wear, the kospet m3 is built around the themes the listing emphasises: an AMOLED display, a long list of sports modes and a set of tracking features. Heart rate, blood oxygen, blood pressure and stress levels are named in the listing as features of this watch. The listing does not say how accurate these readings are, so treat them as features to explore rather than as medical results.
In Bangladesh, the kospet m3 can fit many routines: a commute across Dhaka, a walk or run in the morning, a session on a cycle or rowing machine, or a long day at a desk with music and calls. The listing gives battery figures for several usage levels, so you can judge how often you may need to charge it. Read the battery part of the features section below before you decide.
Key features
The points below follow the feature list in the product listing. Each sub-heading names one part of that list, and each paragraph says what the listing states and what it leaves open.
AMOLED display with 410 × 502 pixels
The listing describes the display of the kospet m3 as AMOLED, with a resolution of 410 × 502 pixels and 331 PPI. These are the figures to compare when you look at screens across our smart watch range, and they are the first details to check if clear reading matters to you. The listing does not give a screen size in inches, so that measurement is not confirmed here. If the size matters to your decision, ask us before you order. Outdoors on a Dhaka afternoon, glare and heat are everyday conditions, and the listing does not say how the display handles them, so ask us about that as well.
170+ sports modes and movement recognition
For the kospet m3, the listing gives 170+ Sports Modes, along with a Smart Recognition feature for six sports movements: Walking, Running, Cycling, Elliptical trainer, Rowing machine and Still. For a commuter who walks to the bus stop, a runner on a morning route, or someone who uses a rowing machine at home, that list shows the kinds of activity the listing names. The listing does not explain how each mode is started, so follow the maker’s instructions for that step. Choose the sports you do most often and check that they appear in the list before you buy the kospet m3.
Heart rate, blood oxygen, blood pressure and stress levels
The listing names heart rate, blood oxygen, blood pressure and stress levels among the features of the kospet m3. These are listed features, and the listing does not describe how each reading is taken or how accurate it is. For general everyday awareness, treat any reading as extra information alongside your own judgement. Do not use a reading from the kospet m3 as a diagnosis, and speak to a qualified clinician about any health concern.
Calling system and music player
The listing includes a calling system and a music player in the feature set of the kospet m3. Together these make it a watch you can use on the move, for example to listen to music on a commute in Dhaka or to keep an eye on incoming calls during a busy day. The listing does not state the call quality, the speaker type or the working range of the connection, so do not assume those details. Bluetooth is the only connectivity type the listing names for this watch.
Battery life and magnetic charging base
For the kospet m3, the listing describes a Li-ion battery of 480 mAh with a magnetic charging base. It gives several battery life figures: up to 12 to 15 days in a typical usage scenario, up to 5 to 8 days in a heavy usage scenario, up to 2 to 3 days in AOD mode, and up to 30 to 35 hours of continuous exercise with GPS. These are the maker’s figures, so your own results may differ with settings and habits. Charge this watch fully before first use, and plan charging around the scenario that matches your week rather than the best-case figure.
Everyday care and storage
Care for this watch is simple. After sweaty sessions, wipe the case and strap with a soft, dry cloth and let them dry before you charge the watch. Keep the kospet m3 away from direct heat, which matters in a Bangladesh summer when a parked car or a sunny windowsill can become very hot. Avoid harsh cleaning products on the screen and the strap, and follow the maker’s instructions for any other care steps.

How to use and set up
Before you start using the kospet m3, check that the model on your order matches the listed name, KOSPET TANK M3 Ultra Smart Watch. Charge the watch fully before first use, and follow the maker’s instructions for the magnetic charging base. These two steps cover the basics without assuming anything the listing does not say.
The listing names KOSPET FIT as the app support. Download the app on your phone, sign in if the app asks you to, and then pair the kospet m3 with your phone over Bluetooth. The listing does not describe the pairing steps in detail, so follow the on-screen prompts and the maker’s instructions for each stage.
Plan the first week with the kospet m3 around your own routine. Start with the sports you use most, and check the battery after a day of normal use so you learn how quickly your own settings drain it. Treat the listed battery figures as a guide rather than a promise, and you will avoid most surprises.
For Bangladeshi conditions, keep your kospet m3 charged before heavy days. Load-shedding can happen at short notice, so a fully charged watch is less likely to run out during a long commute or a workout. Charge it when mains power is available rather than waiting for the battery to run low.
Store the kospet m3 in a dry place at room temperature when you are not wearing it, away from direct sun and damp surfaces. Keep the charging base and the watch together so you do not have to search for them before a busy morning. Check the charge again before you need the watch for a long day.
Keep your order details to hand until you are sure the watch suits your routine, since the return window in our policy runs from the date of delivery.
Compatibility and what is in the box
The listing gives app support as KOSPET FIT, for Android 5.1 and above and iOS 10.0 and above. Check your phone’s version before you order the kospet m3, because a phone below these listed versions is outside what the listing covers.
The listing names Bluetooth as the connectivity type and gives no further version number. If you plan to pair the kospet m3 with a second device, the listing does not say whether that pairing is supported.
The listing does not state which items come with the watch, so we cannot confirm the contents of your order from the listing alone. Ask us about the contents before you order if they matter to you.

Who should buy it in Bangladesh
The kospet m3 suits several kinds of buyer. The scenarios below describe realistic uses based on the features the listing names.
Commuters in Dhaka who want music and call features on the wrist may find the kospet m3 a useful match. This is especially true for people who spend long periods on buses, in traffic or on foot, where a wrist display can be quicker to check than a phone in a bag.
Runners, cyclists and gym-goers who want a long list of sports modes should look at the kospet m3 closely. The listing gives 170+ Sports Modes and up to 30 to 35 hours of continuous exercise with GPS, so the battery figure for longer sessions is a useful part of the decision.
Office workers who want to keep an eye on calls and music during a long day at a desk may also consider the kospet m3. The calling system and music player are the features most relevant to that routine, though the listing does not describe call quality.
Home users who train indoors on a rowing machine or an elliptical trainer will find both named in the Smart Recognition list. That makes this watch relevant to home training as well as outdoor sport, provided the sports you use appear in the listing.
People who want to track heart rate, blood oxygen, blood pressure or stress levels as part of a general routine will find these features listed. Keep in mind that the listing does not describe their accuracy, so read them as personal information rather than clinical results.
