For sale ($3,475 OBRO) have my genuine Omega Seamaster Professional 300M Chronometer, Reference 2230.50.00 (also known by many as the Non AC Dial Seamaster Professional).

This particular model comes from factory with a 18K white gold bezel insert just like the limited edition Omega Seamaster Americas Cup 2533.50 but with the standard dial wording of the 2254.50.00 (hence the nickname non AC Dial) but with raised Omega symbol and metal index markers, giving it a very nice look (only Seamaster from this era to have this). More details of this model can be found at:

The case has brushed sides with contrasting polished case top. The black dial and the hands have a beautiful green lume as shown; the sapphire crystal is in very good conditions. The original 1610/930 Speedmaster style bracelet measures approximately 7 inches so should fit at least a 7 1/2 inch wrist when installed on the watch head (comes with 2 half links, which help a lot in fine tuning the length / centering the clasp in your wrist; has some swirls and marks as shown and very little stretch as shown.)

The watch runs on the trustworthy Omega caliber 1120 movement. The watch was serviced by Omega in 2022 (paperwork included); on my time grapher, when facing up, the watch is running at +5 seconds with an amplitude of 273 and beat error of 0.0s. The watch head is in good conditions; few swirls and small marks as shown. The rotating bezel and white gold bezel insert have a few marks as shown. The back of the case shows some scratches from previous bracelet changes (not visible when wearing the watch; could be polished if desired). The watch and bracelet have not been polished while in my possession (have owned it for about 1 year).

The watch has 2 upgrades done with Omega OEM original parts (done by my watchmen, pressure tested after the work): Planet Ocean second sweep hand with orange tip and the 2500D font date wheel (original second sweep hand and date wheel are included on sale). Am also including an used, 2254.50.00 black bezel insert so new user can wear it with the 18K WG bezel or with the black bezel insert achieving the look of the 2254.50 but with the nicer dial of the 2230 model.

1- Very good conditions 20 MM Omega Speedmaster style bracelet, reference 1610/930 (7 inches long).
