Looking for info on 501 Seamaster 2848 2846 SC (352 inside case)

Educated guess movement no. and 352 being the caliber. Here's a similar caseback from another Seamaster which was listed;

Do you have pictures of the movement? I'm taking a stab that the 'portrait profile' is a gold hallmark.

I think the information request is about this:



1. The Helvetia Head is a Swiss hallmark, denoting 18K Gold.

2. The “352” in the hammer head is a Swiss Responsibility Mark. This denotes the case maker as Serva, SA.

3. The 18K and 0,750 marks are fairly obvious marks for 18K gold.

4. The 2846 and 2848 denote the case reference or model numbers for your watch.

Note that one case reference number might have multiple case metals from steel up through solid gold.

5. The 116460 represents an internal serial number or patent number and is not relevant for this discussion.

For any more information, we would need to see the rest of the watch, including the dial and movement.

Hope this helps,
