Casio moon phase watch

Start with how you’ll mainly wear it: for casual everyday looks, or for outdoor/marine use where extra features matter. In this moon phase line you’ll find models with 100-meter water resistance and resin builds like the WS-1700H-8A, which also shows moon data and a moon phase graph, as well as tide graphs for date-specific coastal planning. If you want a model focused on navigation and travel, consider an option with world time and dual time features, such as some WS-1700 series variants.

Moon data shows the moon age for a given date and a moon phase graph, helping you track lunar cycles at a glance. Tide graph displays the tide level for a specific date and time, which is useful for outdoor activities near the coast. In this watch family, these functions are integrated alongside practical timekeeping, making watches like the WS-1700H-8A and WS-1500H-3BVDF valuable for marine plans or fishing trips.

A traveler prioritizes features like world time and dual time, which are found in several WS-1700-series models designed for global use. A marine or fishing enthusiast benefits from tide graphs, fishing/marine-oriented modes, and strong water resistance, as seen in watches with 100-meter water resistance and moon data like the WS-1700H-8A and WS-1500H-3BVDF.

Rinse after exposure to salt water and dry with a soft cloth to prevent salt buildup, then store in a cool dry place away from direct heat. Because many models in this range come with a 1-year warranty, follow the manufacturer’s guidance for battery changes and servicing to maintain accuracy and performance over time.

These watches commonly use a resin case and resin band, which helps keep the models lightweight and durable for casual and outdoor wear. Some models also feature robust mineral glass for scratch resistance, and the lunar-phase functions are integrated into a reliable analog or digital platform depending on the specific model.

Yes, both digital and analog options exist in this family. Digital models often emphasize moon/tide data and practical functions like dual time and world time, while analog options provide moon phase dials or multiple sub-dials for the moon phase display, giving you a traditional watch feel with lunar-tracking benefits.
