Specifications to check before purchase

• The battery is listed as both over 450 mAh and 1,000 mAh. The claimed standby battery life is up to 100 days, but it is not consistently specified for normal use.
• Offline maps and navigation are claimed by the seller, without confirmation of coverage or availability in your country. Check functionality and required apps before relying on navigation.
• Water resistance is claimed as 10 ATM and IP68, but no verifiable documentation is provided for the model. Avoid swimming and diving until the certification is confirmed.
• Compatibility is generically listed for Android and iOS, without minimum versions. Check the availability of WearPro, permissions, and notifications in your market.
• The seller's title uses “T‑Rex 3 Pro,” but the listing identifies it as GUHUAVMI DTG1 and the WearPro app. There is no documentation regarding authenticity or affiliation with Amazfit; check the model, warranty, and support.
