What "100M Water Resistant" Actually Means

Every Rifino is rated 100 meters water resistant, and that number gets misread constantly — people assume it means you can dive to 100 meters wearing it. You can't, and no watch at this price point should claim you can.

Water resistance ratings are tested in controlled lab conditions, not real-world ones, and they don't account for movement, temperature changes, or the seals aging over years of wear. In practice, 100m means: swimming, showering, caught in the rain, washing your hands without thinking about it, even recreational snorkeling — all genuinely fine. What it doesn't mean is scuba diving, or pressing any buttons underwater (water pressure can force water past the crown seal when it's not fully screwed down), or assuming the rating never degrades. Seals compress and wear over time; a watch that was 100m-rated five years ago isn't guaranteed to still be there today without maintenance.

So: wear it in the shower, wear it in the ocean, don't overthink it day-to-day. Just don't take it scuba diving, and don't go years without ever having the seals checked if you're wearing it hard. That's the honest version of what the number on the caseback actually buys you.
