Absolutely (yes), if you are building an all-gen watch (or, possibly, all gen except for the mid-case & you have an exceptionally accurate aftermarket mid-case) & you are missing is the dial. Otherwise, probably not.
Very nice dial.
I have not found a source for consistently good aftermarket hands. All appear to be luck-of-the-draw. My best & worst handsets came from DW (listed as same part).
For reference, a low amplitude means that gravity & acceleration will have more of an effect on timing. In simple words, timing variations are likely to occur day-to-day.
I agree with the previous recommendations. You need to remove the balance & inspect it carefully. If the watch is running fast, most likely the hairspring is crimped or tangled on an adjacent wheel or bridge. Also, check to be sure the cap jewels (both upper & lower) have reset to their center/null positions in the shock assemblies.
Ditto. An amplitude below 260 may be due to insufficient charge of the mainspring or a dirty movement, but 200-ish may indicate a problem with the balance/hairspring.
I have cleaned a number of gloss dials with (clean) rodico & never left the slightest mark (& I am neurotic about those things). But can you give me some details on that optical cleaning solution?
Well, I did say $500+. That is the '+' I was talking about.
All kidding aside, it is alot of cash, but, in the context of vintage Rolex, quite reasonable since I paid more than $500 for my pre-owned 5513 dial.
Hard to say whether the bezel is gen (this is a case of buy the seller before you buy the part), but the insert is either gen or an extraordinarily good fake.
Without an (original) sales invoice from Rolex (the 1 in Switzerland) or something (verifiably) similar, complete NOS (new old stock) kits like this should always be considered highly suspicious. Unless, of course, you are willing to get duped.
On some cases, a knife blade may not fit in between the ring & case, but a razor blade in a window scraper will. In some cases, I have spent 20 minutes working a window scraper blade around a ring before I was able to create enough space to move up to a knife blade. You just have to be patient & work carefully &, eventually, it will come off.
