I enthusiastically agree that you're entitled to your opinion, and to be sure, I have no mission to alter your perceptions. Having said that, context matters, since it sounds like your opinions come from a
recollection of an experience.
I have an OP 36 and the two most recent Explorer 1 versions all on my desk. The 39 Exp 1 is now 5-years old and is "semi-retired, in storage", but the other two are less than 6-months old, in regular rotation, bought new from my AD, and I wear the crap out of my watches.
The OP's clasp has a very similar hinged lip and internal hook grasp mechanism to the Exp 1. The OP is solid, reliable, doesn't rattle, doesn't give anything close an impression of being some manifestation of a cost-savings shortcut of a clasp. The bracelets on modern steel Rolexes are frankly awesome, in my opinion, and my OP is totally up to that standard. Something you'll have to take on faith: I'm no Rolex fanboy; If I had any grievance with the OP, I would be incapable of holding back.
OP's crown logo looks to be debossed into the clasp, and not engraved as you mentioned, but I get the gist of your comment about that. (Engraving would leave tool marks, I'd expect, and I see none under 10x loupe.) Did debossing give Rolex a minuscule cost savings? Probably. You feel debossing is therefore "unrefined" and that's as valid as not caring at all about that detail. But I can see no mechanical or quality issues at all with my OP, nor have I any grievances at all with the watch that I've owned and worn since getting it. It's been solid. It's been great, and a fun size and color to wear.
You recall a different experience, and that's valid as far as a recollection can go.
