TORJALPH TJ37 Smart Watch

Here is the whole job description, and it covers what most beginners use every day:

• Time and faces: a 1.83-inch full-touch colour screen at 240 × 284, with more than 200 watch faces in the Da Fit app.
• Activity: steps, distance and calories, plus a sedentary reminder when you have been still too long.
• Health: heart rate, blood oxygen, blood pressure and sleep, measured through the day and night.
• Alerts: calls, texts, WhatsApp, Facebook, Twitter and Messenger pop up with the sender's name.
• Handy extras: alarm, stopwatch, timer, weather, music control and a remote shutter for the phone camera.

Calls work one way on the TJ37. The watch shows who is ringing and lets you hang up, but the conversation stays on the phone. For a first watch that is often a plus: fewer menus, fewer permissions and a longer battery.

The silicone strap is sweat- and dust-resistant and breathable, which matters for a watch you will wear to bed. At 1.44 ounces the whole watch stays light enough for sleep tracking.

Use the modes to build a balanced week:

1. Two walks or easy runs: keep heart rate conversational and let the step count climb.
2. One sport session: badminton, basketball or football for variety and fun.
3. One rope-skipping block: ten minutes of intervals is a quick cardio hit at home.
4. One rest day: no session, but keep the watch on for resting heart rate and sleep.

Heart rate, blood oxygen and blood pressure are all measured on the wrist and shown in real time. Treat them as trends rather than medical readings. Wrist optical sensors are good at showing whether today's effort was harder than last week's, and blood pressure from a watch is an estimate, not a cuff result.

Sleep that makes sense in the morning

Wear the TJ37 to bed and Da Fit breaks the night into a sleep record you can compare week by week. Look for patterns such as later bedtimes before bad sleep scores, rather than chasing a perfect single night. Consistency beats precision.

For a side-by-side view of how budget watches handle steps, sleep and water, the honest review of FitPro-style watches covers the limits.

1. Charge the TJ37 on its magnetic cable until full; the first charge takes about 3 hours.
2. Download Da Fit via the manual's QR code and register.
3. Switch on Bluetooth, then approve the notification, call and SMS requests Da Fit makes.
4. In Da Fit, add a device and pick the watch from the scan list; it may appear as TS29 or Q50.
5. Choose a watch face and set your step goal.

Skip pairing in the phone's Bluetooth settings first. Doing so can hide the watch from Da Fit's scan, and a new watch that will not show up usually traces back to it. If that happens, forget the watch in Bluetooth settings and scan again from the app, as covered in keeping a watch paired.

Battery and charging

A 230mAh battery gives 5 to 7 days per charge. Constant heart rate tracking and lots of notifications land you closer to five, while a quieter week stretches toward seven. Charging twice a fortnight, on fixed days, is an easy rhythm to keep.

• The magnetic charger snaps onto the back; make sure both contacts sit flat.
• Towel off pool water or sweat before the TJ37 goes on its cable.
• Any USB port or phone adapter works.

Run through these checks before you order:

• Screen size: the TJ37's specifications give 1.83 inches at 240 × 284, although its product name mentions 1.69 inches. The resolution matches the larger figure.
• Water: IP68 with a 1.5 m depth rating covers rain, hand washing and pool use near the surface. Keep it out of hot showers, saunas and seawater.
• Sports: twelve modes suit most routines; triathletes and gym-class regulars may want a longer list.
• Warranty: TORJALPH covers the watch for a year.

The TJ37 is also a good pick if a household already runs Da Fit on other watches, since everyone shares one familiar app. For a closer look at how Da Fit compares with other watch apps, see FitPro app setup and alternatives. Straps are easy to refresh later, and band sizing helps match a new one.
