This is a compatible pin and tube that will fit Omega Planet Ocean 45.5mm (Full-size) watch links. If the back of your end link (the part that connects your strap to your watch) has the number 951 or 953 on it or the last three didges of the code on your clasp is 951 or 953 then these will fit your watch. 

These will fit straps with a clasp stamped 1579/951, 1581/953 and 1588/951.

This pin and barrel were not made by Omega but are high quality compatible parts made in the UK and designed specifically to fit the stated watch models.

The tube/collar has the double groove design -the same style Omega bracelets rely on- for a more secure fit with reduced stretch and wear on bracelet components over time.

For Omega watch models 2200.50.00, 2205.50.00, 2200.51.00, 2200.52.00, 2208.50.00, 2210.50.00, 2210.51.00, 2218.50.00, 222.30.46.20.01.001 and 222.30.46.20.01.002 and similar.

I have given you photos of your pin and tubes from every angle. Please use them to add to this description.
