As you know last week I bought a timex luxury sports man watch fitted with one of the highest grade chinese made movements, the seagull st2504. Before I purchased it, the watch was timed at the machine at +8 sec per day, after a week of daily wearing, I have come to the conclusion that this watch is an oustandingly accurate watch.
Here are the results, I observed during a week of daily wearing:
friday 30th january to saturday 31th january: +4 seconds
saturday 31th january to sunday 1st february: +10 seconds
sunday 1st february to monday 2nd february: +0 seconds
monday 2nd february to tuesday 3rd february: +0seconds
tuesday 3rd february to wesdneday 4th february: -1 seconds
wednesday 4th february to thursday 5th february: -3 seconds
thursday 5th february to friday 6th february: -2 seconds
This watch is as accurate as any of my Omegas and also bear in mind that it costs 30 time less what a PO or a sub costs for exactly the same accuracy results. So where does such an accuracy come? The fact that most of the seagull movements have better tolerance and factory adjustment than some swiss movements out of the box. I know a guy who own a seagull moonphase since 6 months and who has an accuracy of +4 sec per week. On the openheart self winding movements from seagull the triovis regulating accuracy system is responsible of such a consistence in the accuracy. The triovis regulating system is a much better regulation device than the etachron which dislikes frequent services and is not very shock resistant.
From my personal point of view, I rate the seagull above the seiko automatics in terms of fit, finish and accuracy. Bare also in mind that the movement in my watch is not a cosced one, imagine if the chinese submitted their movements at the cosc!! The problem with Seiko is that very few watchmakers repair them, many watchmakers dislike the chrono movements from Seiko due to their very poor parts availability and crude finish. The main advange of the seagull or shanghai movements is that they are improved copies of eta, valjoux, piguet and venus movements. Seagull is quality wise on par with Lemania if we are speaking of the chronographs, tourbillons and other complications alone. And accuracy of any seagull movement is excellent out of the box.
Some people will say: "but you can't compare a chinese brand that is unknown to a great swiss brand". I will answer them: "No" for these reasons:
-Chinese with Seagull have developped the same complications on movements than the swiss brands like Breguet and Blancpain: like the handwound column wheel chrono with moonphase, the double tourbillon, the carrousell tourbillon, the flyingwheel with openheart and the minute repeater
-Accuracy even if the watch isn't cosced is more than excellent, just see my results
-the price is 30th or 20 times less than what costs a swiss watch of an equivalent category.
This thread is mainly a food for thought for people thinking that Chinese made watches are inferior to Swiss made watches. For the anedocte, a guy with a 15000$ Blancpain asked me about my Timex Luxury Sports watch, he couldn't believe how much I paid for it. He told me :"That is a more than a lot of watch for the money."
