Both watches are from around the same time period and I would think it will be a close match. The Seagull must have been a true luxury watch for the average Chinese back in the days. This particular Glycine was aimed at the middle class worker wanting a reasonably good quality timepiece. The Sea-Gull is a NOS watch and the FHF has clearly been used, so to even the battlefield I will keep the original mainspring in the Seagull and get a new mainspring for the FHF movement.
I will start with the Seagull
The Seagull looks new.The case is made out of stainless steel with a nice Sea-Gull motive on the case back.Always a good feature to have a dust cover. The case back feels cheaply made with the seagull showing through the back.Movement has some cool decorations.Performance is pretty good considering it has been lying around for 30 years.A positive surprise is the jewelled barrel bridge and centre wheel.The dial side has a rather rough surface finish, but all moving parts have a reasonable finish.I will reuse the old mainspring.Testing that the balance moves freely.Movement back together and ticking.Dial finish is acceptable, the hands have a cheap look to them as the design of the hour and minute hand does not quite match. I do like the red dot on the seconds hand.Watch back together and ready to test the performance.Dial down is very good.Dial Up.Crown down.Crown Left.Crown RightCrown Up.
And now the Glycine
The Glycine needs a little tidy up.Solid stainless steel case.The movement is in good condition No decoration, but finishes (well, brushed …) made for functionality. No doubt this watch needs a service. The FHF also has a date change mechanism and the finishes are slightly better than on the Sea-Gull.Surface finish overall is somewhat better than on the seagull, but the movement does not have a jewelled barrel bridge like the Seagull.The FHF gets a new mainspring to compensate that it is not a NOS watch unlike the Sea-Gull.Testing that the balance moves freely.Movement back together and beating. The hands and dial have a better finish than the seagull.Dial downDial upCrown downCrown Left.Crown rightCrown up.
Performance is slightly better on the Sea-Gull but the Glycine is not a NOS watch. The Glycine dial and hands have an overall better finish than the Sea-Gull and feels more refined. The Sea-Gull movement has slightly better construction with a jewelled barrel bride even though finishes are a little rougher than on the FHF. The Glycine case is more solid than the Sea-Gull case, but the Seagull has a proper dust cover…As I thought, it is a close match indeed. Up to you to decide which one you would want!
