The skull motif makes the RM 52-01 family recognizable across several archived listings. Examine the case finish, dial details and strap rather than relying on the family name alone.
Start with the skull and its framing
In RM 52-01 archive photos, compare the shape of the skull, the surrounding case and the spacing around the dial markings. Look at photos from the front before comparing side details. Similar styling does not establish that two listings describe the same option.
Record finishes and straps separately
Two entries may use the same reference but show contrasting case finishes or straps. Treat rose-tone, black and other color terms as appearance labels unless the archive separately identifies a material. Use the image gallery and the historical specification table together.
Keep the wider RM 052 family in view
The archive groups different RM 052 references together. Read the full title and the exact suffix before comparing variants or historical prices. The price on one skull-dial listing cannot be generalized to other models in the collection.
