Descent G1 Solar vs Instinct 2 Solar Tactical vs fēnix 7 Solar | Watch Design

Garmin Descent G1/G1 Solar Dive GPS Watch

Featuring an easy-to-read, high-contrast display and 45mm watch case, the G1 Series introduces a new compact design into the dive lineup that is purpose built in both form and function. Water rated to 10 ATM (100 meters) and tested to engineering standard EN133319 for dive compliance with leakproof inductive buttons and a sapphire lens, the Descent G1 Series is rugged and ready for excursions above and below the water’s surface. Available in multiple color options and compatible with Garmin QuickFit® bands, divers can switch between long and short straps for wearing over wet suits when needed, or switch up their style in a snap to take their timepiece from a dive to dinner.

Garmin Instinct 2 Solar Tactical Rugged GPS Watch

In addition to its new vibrant color options, Instinct 2 Series offers a slimmer profile, as well as two sizes—a traditional 45mm bezel and a new Instinct 2S with a smaller 40mm bezel, providing a more comfortable fit for individuals with smaller wrists and women (note: the Instinct Solar Tactical is only available in the 45mm size). A new high-resolution, easy-to-read display protected by chemically strengthened, scratch-resistant glass helps customers feel confident knowing they are ready for any challenge. Paying homage to the rugged Instinct and Instinct Solar Series, Instinct 2 remains built to military standard 810 for thermal and shock resistance and is water rated to 100 meters.

Instinct 2 Series is compatible with the Garmin Connect IQ™ store, an all-in-one platform for further personalizing Instinct 2 Series with free downloads of apps, widgets, watch faces, data fields, and more.

Garmin fēnix 7/7S/7X Premium Outdoor GPS Watch

Built for rugged reliability from premium materials like titanium and sapphire, fēnix 7 Series comes in three sizes and has been redesigned for ultra-durability with reinforced lugs and metal button guards. Trusted button controls are matched with a responsive new touchscreen interface for dual utility, improving daily smartwatch interaction, and map navigation. The powerful 5-buttons and touchscreen interface enables quick and intuitive engagement with the topographical maps, offering confident “off-grid” situational awareness. With the introduction of Sapphire Solar models, users do not have to choose between solar capabilities and a scratch resistant sapphire lens, as they had done previously for the fēnix 6 Series. The updated fēnix design maximizes solar surface area for increased efficiency including doubling solar gains from fēnix 6 to fēnix 7 in smartwatch mode.
