Key selling points: - It's incredibly cool. - No resin material is used, so you don't have to worry about band replacement due to aging. - The band doesn't get stuffy and develop odors. - The battery, from my experience with a previous Pro Trek, stayed in a high state even without solar charging for a month, and it's extremely good. - Easy to match with a suit. - The backlight illuminates when tilted, making it easy to see in the dark. - Excellent visibility even during the day. - Feel free to ask any questions. - No case included.
