Hi everyone,

I recently came into possession of this 18k solid gold Omega Seamaster, which has been in my family since the 1960s. I’ve been doing some digging, but I’m seeing some details on this piece that don't seem to match the standard catalog versions I find online, so I'm hoping some of the vintage experts here might recognize this configuration.

Specific Details:

• The Bracelet: It is a heavy 18k gold mesh style. The most interesting part is a hallmark on the clasp that reads "361 VI" next to a "750" stamp. I've found some mentions of "VI" representing Vicenza, Italy, but I haven't seen many Omegas with this specific maker's mark.
• The Caseback: Unlike most Seamasters I see from this era, the caseback on this one is entirely plain and high-polished—there is no Hippocampus logo on the exterior.
• The Dial: It has a really nice textured crosshatch/linen finish that catches the light well.
• The History: This was a personal heirloom from the mid-60s. Given the Italian hallmarks on the bracelet, I’m curious if this was a specific regional release or a custom order through an Italian jeweler. The clasp also has a "Love Roberta" engraving from the original owner, which adds a bit of personal provenance to the piece.

My Questions:

• Does anyone recognize the "361" hallmark or know which workshop in Italy might have been contracted for these bracelets?
• Is a plain, logo-free caseback common for solid gold Seamasters of this period?
• Does this look like a standard Italian-market reference, or something more bespoke?

I've attached photos of the dial, the hallmarks, and the caseback. Thanks in advance for any insights!

Hi everyone,

I’m researching a family heirloom that recently came into my possession: a mid-1960s 18k solid gold Omega Seamaster.

It has a few features I’m struggling to find exact matches for, specifically the heavy 18k gold mesh bracelet and the polished, logo-free caseback. There are some specific hallmarks on the clasp (361 VI and 750) that suggest an Italian origin, but I haven't been able to find much documentation on Omega's use of these specific workshops.

The clasp also features a "Love Roberta" engraving from the original owner.

I’m looking for any insights on:

• The Bracelet: Does anyone recognize the "361 VI" hallmark or know which Italian workshop Omega may have contracted for these?
• Caseback: Is the plain caseback standard for 18k Seamasters of this period?
• Market: Any thoughts on whether this was a standard catalog item or a specific regional configuration?

I've attached high-res photos of the dial, hallmarks, and case. Looking forward to hearing what you all think!
