Contactless payment: Gadget or really useful?

The 255 can pay without a phone. The 165 no. If you're running without a wallet and stopping at a coffee shop, it's convenient. Otherwise, it's marketing.

Honestly ? You have your phone or a map. It's not a game-changer.

Music versions: Embedded music

Both exist in Music versions. You store up to 500 songs directly on the watch. You run without a phone. You listen to your playlists.

The 165 Music costs €249. The 255 Music costs €349. Even 100€ difference.

• Storage: 500 songs on both
• Audio quality: same, depends on your headphones
• Battery: slightly impacted by music, but acceptable
• Interest: True if you run without a phone, false otherwise

Price: The strong argument

165: €199 (or €249 in Music)

255: €299 (or €349 in Music)

100€ difference. It's budget. For a casual runner, this is huge. For someone who runs 4 times a week, it's an investment.

You sometimes find discounts. The 255 goes down to €249 on sale. The 165 at €149. At these prices, the 255 becomes interesting.
