Omega Seamaster

I spotted this Seamaster at auction and couldn't look away. An all-silver case, clean dial, strong proportions. It had the quiet confidence that Omega got so right in the 60s and 70s. The listing photos were concerning though: clear signs of rust on the hands. Any loss of tolerance in watch components can render the movement useless, and rust erodes tolerances aggressively. But the rest looked remarkably honest for a fifty-year-old watch. Something about it felt worth pursuing, so I placed a bid.

Diagnostics

Initial diagnostics when the watch arrived were reassuring. It held a beat, albeit a very slow one, losing about 50 seconds a day. That meant the movement was fundamentally alive, just struggling. Opening the caseback made things more interesting: there were no signs of rust inside. The rust on the hands was surface-level, not systemic.

The seconds pinion was bent, probably from a blockage somewhere in the gear train. One of the keyless works springs had snapped, and the pressure cover along with it. That kind of damage usually comes from someone forcing the crown against resistance, winding or setting the time too aggressively when something was already stuck. It painted a picture: an owner who relied on this watch daily and wasn't gentle with it. Not out of carelessness, but out of familiarity. You don't force a crown on a watch you're precious about. You do it on one you trust to take it.

The movement was dirty throughout. Not damaged beyond the broken parts, just neglected. This watch had been sitting for a long time after years of active service.

I sourced original Omega replacement parts for the keyless works and seconds pinion, then fully disassembled the movement. Every component was cleaned individually, inspected, and set aside for reassembly.

The case told its own story. Light scratching across the surface, consistent with years on a wrist. Nothing deep, nothing suggesting drops or abuse. The honest patina of a 70s daily driver. I polished the crystal to restore clarity but left the case finishing untouched. The hands stayed as they were too, rust and all. I could have cleaned them up or sourced replacements, but that would have erased something true about this watch. It was someone's daily companion for years. It went places, took knocks, kept time through all of it. Omegas of this era were built as workhorses, and this one had clearly lived that life. My job was to make it run again while respecting what it had been through.

With new parts installed and the movement fully reassembled, I put it on the timegrapher for initial readings. The results were promising. After careful regulation, adjusting beat rate and positional accuracy, the movement was running precisely and consistently across positions. Everything cased up, crown function tested, rotor spinning freely. The Seamaster was back in service.

Fifty years in, a new chapter. Same scratches, same hands, same story. Just a heartbeat again.
