The difference is:

Suunto Sparta watch is the benchmark of GPS watch industry! Absolutely worthy of the title of top sports watch (excellent accuracy and stability), Garmin watch is second only to it, but it is also a very good choice!

Songtuo and Jiaming are both outdoor sports watches. Songtuo belongs to Tuoye series products, and its target population is mainly users engaged in outdoor adventure activities, including lightweight sports and fitness users. On the other hand, Jiaming is a combination of mobile phone and watch products. In addition to the aforementioned user groups, Jiaming also serves professional surveying and mapping users.

In terms of appearance, Songtuo has been designing and producing watches for many years, while Jiaming is committed to the research and development of GPS navigation products. Therefore, Songtuo's watch products look more chic and fashionable. Jiaming has made different material choices for their dials in order to give consideration to the stable reception of GPS signals.

In terms of functions, Jiaming specializes in GPS-related products, and the family of GPS watches is also huge, with rich accessories, and the price of accessories is much more generous than that of Songtuo. Generally speaking, Jiaming is more cost-effective and professional.

3. As far as GPS positioning is concerned, there is a great god abroad who commented on it, and the ranking order is Sparta, Tuoye 3 and Jiamingfei 3. Of course, he has not only tested these three models, but also a bunch of GPS handheld devices. And at least visually, Sparta is the best of all sports GPS watches at present, with clear fonts and clear chart guidance, which is highly recommended.
