Omega Seamaster 168.023 / 166.032, Caliber 751 Day / Date Chronometer Movement, Just Serviced

SOLD ($595 OBRO) I have an Omega Seamaster Day Date with a caliber 751 automatic chronometer, movement. Some features of this model are as follows:

Model: Seamaster 168.023 / 166.032: the inner side of the caseback shows both reference numbers; 166.032 is the non chronometer model (caliber 752) while 168.023 has the caliber 751 chronometer movement. Based on the fact the sparkle dial does not says chronometer on its wording either the watch was originally a 166.032 which got an upgraded caliber 751 movement or a 168.023 chronometer model which got a non chronometer replacement dial.

Size: Approximately 36.5 MM.
Case: Stainless steel, approximately 42 MM lug to lug. The case has been brushed / polished in the past and has a few marks but in good conditions for a 50 year old watch.
Dial: Silver sparkle.
Crystal: New plexiglass.
Serial number: 30 million (about 1969 production).
Movement: Omega in house chronometer caliber 751, 24 jewels, 19,200 beat rate, 49 degrees lift angle, date and day functions; quickset for date. Just serviced; movement running at +2 SPD with an amplitude of 263 and a beat error of 5.5 ms.
Bracelet: Aftermarket 19 MM brown band with silver buckle.

I am surprised no one has already written this:

A 168.023 has a cal 751 and has "Chronometer Officially Certified" on the dial.
A 166.032 has a cal 752 and the dial of the above shown version.

So... the watch in question has either had its dial or movement changed at some time.

None of the reference numbers has hands like this watch. That is for certain.

This is a forum for enthusiasts. Not mentioning the above might lead to a very disappointed buyer.

Am certainly not an expert in them, it was like that few years ago when bought it. The caseback has both reference numbers in the inner side (168.023 and 166.032) so could had been originally either model and like you said got the dial / hands / movement swap over time. Have revised the title and description to reflect the fact may in fact be a 166.032 with an upgraded caliber 751 movement or a 168.023 with a replaced dial. I have seen different hands on 168.023 / 166.032 so have no idea about the “correct” hands for these models. Keep in mind this is over 50 years old.
