Our verdict

Meant for a buyer who wants a stated screen type and size, a battery capacity and a battery life, with four colors at $74.99. It does not cover strap material, water resistance, compatibility or any validation for the health functions the listing names. The main caveat is that the listing names no maker and gives no figure behind its feature list, so each feature is a claim.

Best for
Someone who wants a smart watch with a stated screen size and battery capacity in four colors and treats the feature list as claims.
Skip if
You need a stated strap material, water resistance figure or compatibility line, since the listing gives none of them.

The title leads with K70A, and the page prices the watch at $74.99 across four color options. The listing gives a 2.13 inches AMOLED screen, a 480 mAh battery and a battery life of 7-14 days, then lists heart rate monitoring, blood pressure measurement, Bluetooth calls and blood oxygen detection among its features. The listing names no maker, strap material or compatibility line.

Options and pricing

Four colors are orderable: Black, Silver, Black Camouflage and Silver Green Camouflage, all at $74.99. The listing's own color line spells the last two as Black Camo and Silver-Green Camo. No option changes the price, and the listing does not say whether the camouflage versions differ from the plain ones in anything but pattern.

How it compares

The Blood Pressure Heart Rate Monitoring Touch Screen Smart Watch starts at $69.76 and its listing gives a 1.65 screen size, against the 2.13 inches here. The For Huawei Xiaomi NFC Smart Watch Men GT3 Pro AMOLED 390*390 HD Screen starts at $75.92 and its listing gives an electronic movement type and a Professional Waterproof line, neither of which this listing gives. The Color 1.04 round screen bluetooth smart bracelet is $78.67 and its listing gives a 1.04 inches screen.

Shipping

  • What the shipping page says. Complimentary ground shipping in 1 to 7 business days, in-store collection in 1 to 7 business days, and next-day and express options, with a pointer to delivery FAQs for methods, costs and times (checked 2026-11-11).
  • What the FAQ says. Orders are delivered from the store's "global bases factories": about 1 to 4 days of processing, then 7 to 18 days of shipping, 2 to 4 weeks in total, with tracking after processing; another answer says dispatch from the factory in 2 to 3 days and up to 10 to 12 days with the carrier. It adds that post-office limits can delay parcels and that an order cannot be cancelled after 24 hours.
  • Free shipping. The cart's free-shipping bar (in the store's page code, not a policy page) says free shipping on orders over $500. The pages we read state no shipping price for smaller orders.
  • Taxes and duties. The FAQ says the store is not responsible for international taxes and duties, and that duties and shipping fees are not refunded on a return or exchange.
  • Where it ships. The FAQ answers "Do you ship worldwide?" with yes and names no country. Nothing names the US, Canada, the UK, Australia or New Zealand, so confirm before you pay. A wrong address entered by the customer is the customer's responsibility once the parcel has left.

Returns and warranty

  • Returns. The refund policy gives 30 days after receiving the item to request a return. The item must be as received, unworn or unused, with tags, in its original packaging, with proof of purchase. Email [email protected] to start; the store sends a return label if it accepts the return, and items sent back without a request are not accepted. An unboxing video is required to process any refund (checked 2026-11-11).
  • Not returnable. Custom products (special orders or personalized items), perishable and personal care goods and hazardous materials cannot be returned, and the policy says it cannot accept returns on sale items or gift cards. Approved refunds go to the original payment method after inspection.
  • The pages disagree. The shipping page calls returns and exchanges "easy and complimentary, within 14 days", against 30 days in the refund policy, and the FAQ says duties and shipping fees are not refunded. Ask the store which applies before you order.
  • Faulty or wrong items. The FAQ says to email a photo and the order number to [email protected] for a faulty item, or a wrong size that was ordered correctly, and that the store then sends a free reshipment without taking the item back. No warranty terms appear on any page we read.

Discount code

  • The code. FACESTORE (labelled "25% off") is the discount code attached to this site's affiliate account for the store. The label is the code's own, not a price we checked: we did not test whether the code applies to this item, or what it takes off at checkout.
  • What the store says about discounts. Its pages give no discount-code rules. The refund policy says sale items cannot be returned and does not say whether an item bought with a code counts as one; the Terms of Service say the store may correct errors in pricing, promotions and offers, change prices without notice and cancel orders, even after you have ordered (checked 2026-11-11).

Before you buy

Aviationkart's homepage title calls it the "World's Largest Aviation Shop", but its catalog of about 3,000 items covers apparel, shoes, bags, mugs, headsets and gadgets as well as watches and jewelry. The About page calls it a family-run business that ships worldwide; the contact page gives an email address and "Munich, Germany", and the Terms of Service say the laws of India govern them (checked 2026-11-11).

This listing is a marketplace-style product sheet: the text is a supplier-style "Product information" list, and the FAQ says orders are delivered from the store's "global bases factories". Statements about materials, purity, plating, gemstones, brand and movement are the listing's own claims, which we could not verify.

The listing's sensor and health statements (blood pressure, heart rate, blood oxygen, body temperature, sleep) are its own. We did not test any of them: treat the readings it describes as unverified, not as medical measurements.

Independent coverage: none found for this product. The only independent page found for the store is a small Trustpilot listing (7 reviews, TrustScore 2.9 when read on 11 November 2026, six of them one-star), whose newest review, dated 6 October 2026, says two expensive watches were ordered and two cheaper, different models arrived. Other reviewers there allege items that did not match the photos, unanswered support and, in one case, fraud over a drone order; one five-star review praises quality and delivery. Trustpilot does not confirm what reviewers say, and neither could we.

What we liked

  • The listing gives a screen size, a screen type, a battery capacity and a battery life on separate lines
  • The four colors, plain and camouflage, are all $74.99
  • The listing gives a suitable-for line that covers women, men, teens, couples and adults
  • The listing names a watch, a manual and a data cable in the package

Worth noting

  • The listing gives no strap material, case size, water resistance figure or compatibility line
  • The title leads with K70A and no line in the listing says who the maker is
  • The listing says it covers heart rate, blood pressure and blood oxygen but offers no accuracy figure or validation
  • The listing gives a battery life of 7-14 days without saying what use that assumes

Questions before you buy

What screen and battery figures does the listing give?

The listing gives a 2.13 inches screen of type AMOLED, a battery capacity of 480 mAh and a battery life of 7-14 days.

Which features does the listing name?

The listing says heart rate monitoring, blood pressure measurement, social entertainment, Bluetooth calls, smart notifications, remote selfie control, sleep monitoring and blood oxygen detection. It gives no figure for any of them.

Do the four colors cost the same?

Yes. All four, Black, Silver, Black Camouflage and Silver Green Camouflage, are $74.99 according to the listing.

Can I return it if I change my mind?

The refund policy gives 30 days to request a return of an item that is unworn or unused, with tags and original packaging, and requires an unboxing video for any refund. It says sale items cannot be returned. The shipping page says 14 days instead, so ask the store which applies.

How long does shipping take?

The store's pages disagree. The shipping page says complimentary ground shipping in 1 to 7 business days; the FAQ says 1 to 4 days of processing plus 7 to 18 days of shipping, 2 to 4 weeks in total, from factories. Duties and taxes are the customer's, and the cart bar mentions free shipping over $500.

Does Aviationkart ship to the US, Canada, the UK, Australia and New Zealand?

The FAQ says yes to worldwide shipping but names no country, and no page we read lists the US, Canada, the UK, Australia or New Zealand. Confirm with [email protected] before you pay, and ask what shipping costs on an order under $500.

Does the FACESTORE code work on this item?

We do not know. FACESTORE (labelled "25% off") is the code attached to this site's affiliate account; we did not test it on this item. The store's pages give no discount-code rules, and its refund policy says sale items cannot be returned.

Independent

What we couldn’t verify

  • The listing says the features include heart rate monitoring, blood pressure measurement, Bluetooth calls and blood oxygen detection, gives no accuracy figure or validation, and none of it was checked here.
  • The listing names no maker, strap material, case size, water resistance figure or compatibility line, and K70A appears in the title only.
  • The listing gives a battery capacity of 480 mAh next to a battery life of 7-14 days, and it does not say what use that battery life assumes.
  • The listing's material, brand, sensor, battery and water-resistance statements were not verified; we did not open, wear or test the watch, and read no accuracy figure or validation for its sensors.
  • We found no independent review of this product, and the store's own pages are the only source for its description, price and policies. Trustpilot's small page for the store has complaints about other items.
  • The store's pages disagree on delivery time (1 to 7 business days, 2 to 4 weeks) and on the return window (14 or 30 days), and none lists the US, Canada, the UK, Australia or New Zealand.
  • Whether the FACESTORE code applies to this item was not tested; the store's pages give no discount-code rules.
