Summer fashion is lighter. Roll up your shirt sleeves, wear shorts, and add sandals and sunglasses. In a season where layering doesn't create depth, the wristwatch on your wrist greatly influences your style. Lightness, practicality, playfulness of color, and a definite presence that works on your wrist. Summer watches give a clear outline and playfulness to summer clothes that are not just cool. Whether you're walking around town, heading to the beach, or spending an afternoon on the terrace, the impression you give changes dramatically depending on the watch you choose. Here, we propose summer outfits that make the most of summer watches, divided into six categories.

Advice from the editor-in-chief of Kronos Japan!
Key points for choosing a summer watch

After working as a salaryman, he began working as a watch journalist in 2004. He contributes to watch and lifestyle magazines both in Japan and overseas, and also serves as a lecturer at seminars and events for watch and luxury brands and retailers, and as a radio personality on the radio program "BEST ISHIDA presents Chronos Japan Edition Tick Tock Talk♪" (every Saturday night from 25:00 am to 25:30 am @TOKYO FM). He has interviewed numerous people involved in the watch industry, including CEOs and R&D and planning staff from companies based in Europe, including Switzerland, Germany, and France. He has been in his current position since 2016.
Summer watches are perfect for getting into the summer spirit. Their vibrant colors and sporty designs are ideal for the active season. However, things like protruding edges and bracelets that stick to your skin, which aren't a concern in other seasons, can become quite annoying in the sweaty summer heat.
So, if you're choosing a summer watch, put aside other people's opinions for the moment and choose one that feels comfortable for you. Also, if you wear your watch in the summer, I recommend wiping off any sweat or dirt after use. This simple step should significantly extend the life of your watch.
