I think there should be some offense taken by someone insisting something gives off a "dad vibe" as their main reason for not recommending the increased cost of this device. Is this a fashion device or is it a piece of high-tech equipment whose additional feature, made with superior materials, enhances use? Make no mistake, the bezel enhances the Watch's usability, nevermind that, much like Viking79 notes, the bezel has saved my phone's screen on multiple occasions. There's a reason Samsung is still including it as a main feature.
The price difference of $100 to include a waterproof rotating bezel and an upgrade in material durability is 100% justified.
And if we are trafficking in sexist tropes like "dad vibe," I will counter that perhaps the meatier bezel option, in addition to being a usability enhancement, is also a purposefully more-masculine design aesthetic. And it's one that can be better appreciated by a male user, who posses in general, larger bones and more muscle around their arms. A meatier watch looks better-proportioned on their wrist, and it may be something they desire.
I don't think a woman would appreciate a man reviewing women's accessories and dismissing them for having "grandma vibes" or "little girl vibes" or "unprofessional vibes," so I'm thinking maybe a woman shouldn't pass judgement on the kind of aesthetics a man desires in their tech equipment. Especially, again, when that aesthetic enhances usability as opposed to detracting from it.
