Depending on what you want
- If you plan to swim with it, take the Timex Deep Water Reef 200 Titanium Automatic TW2W73800 instead: water-resistant to 200 m, at €465.52.
- If you want to spend less without losing anything on the spec sheet, the Citizen Tsuyosa Shore NJ0234-58X costs €349.
- If you like the model but not this version, see the Laco, at €440.

- Automatic movement. It winds itself on the wrist, with no battery, using calibre Laco 2S (base Miyota 82S0), seconde stop.
- Sapphire crystal. The most scratch-resistant option.
- Priced below the brand median. It costs 53% less than the median of the 13 automatic Laco watches in the catalogue (€930).
