Hands should look like a set. The hour hand and the minute hand share a color and a finish, and they clear each other as they pass. A second hand that sits high will cast a shadow you can see at an angle. A hand that was swapped later often mismatches the luminous plots in color even when the shape is close. Sight along the dial from the side and see whether the hands are parallel to the chapter ring or droop toward it. Droop can be a bent pipe or a loose cannon pinion. Either one is something to name in the note, not something to hide behind a slogan. The check is visual and it does not require taking the watch apart.

How it differs

The dial opening and the bezel width trade space. A narrow bezel leaves more dial. A wide bezel hides it. Describe which way this model goes. For the Tourbillon Esqueleto Rd505sq, keep the comparison inside this case idea and do not borrow a paragraph from the neighboring model.

Common mods

Bezel inserts fade, crack, or sit loose. Any one of those is enough for the sentence. You do not need all three. On the Tourbillon Esqueleto Rd505sq the useful sentence names one changed part.

What to check on a used piece

Inspect the luminous plots against the hands, the date window if there is one, and the pusher action if the model has pushers. Apply that list to the Tourbillon Esqueleto Rd505sq and stop when the three checks are written.

A library page is written by {Site}. A photo post is one person’s notes. Neither authenticates a watch, offers it for sale, or speaks for the name on the dial. These notes are not authentication and not a shop.
