This Submariner came in, and on first sight, nothing was wrong with it…. Continue reading
Sometimes, it’s hard to understand what engineers were thinking when looking at some watch movement features. One of the worst offenders I can think of is the otherwise excellent Valjoux 7750 chronograph movement.
Try to change the date with the quick-set function too close to midnight, and you are in for a surprise – a sizeable repair invoice from your watchmaker!
Have a look at this Valjoux 7750. Next to the “14” on the date disc, you can see the brass coloured date change wheel, and the little triangular bit that should advance the date has broken off. You can see the same wheel as the day change wheel on the left and above, with the triangular tip intact.
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.
This watch probably dates from the early 80s, as the dial is already in Chinese and English, and the movement is the 17 jewel Tongji. Continue reading
And whilst we are at it, here is the video of me taking apart the movement:
It’s been a while since I’ve put up a video, and I always wanted to do one of me putting together a watch movement. A bit tricky, as you are of course more nervous with the camera running, and because I can’t use the microscope whilst filming (as you wouldn’t be able to see anything), so I have to do all the things I usually do under the microscope just with the optivisor.
Nevertheless, here we go:
Torsten, who is very active on the WUS Chinese watch forum, has asked me to compare three movements for him. The original, the ETA 2824-2, and the well known Sea-Gull ST2130, a Chinese clone, and the new Peacock SL3000, another Chinese clone.
I have a new Sea-Gull in stock, and Torsten sent me a Peacock. Thanks to Ron from Texas, I got hold of a used Fortis watch with an ETA2824-2, so we have to take into consideration that the ETA isn’t new, but used. Continue reading
I chose the yellow one, because I liked the colour best, and the main reason for the buy was to find out how accurate a super-cheap quartz watch is!
This is a watch from my collection – a Sea-Gull 1963 chronograph. It’s a replica of a chronograph Sea-Gull manufactured for the Chinese air force in 1963.
The movement is a clone of the Venus 175 movement, which Sea-Gull now calls the ST19.
Just right up my street – no frills, clean dial, just does what it has to do. It’s hand-winding, and has a normal second hand dial at 9 o’clock, and the minute counter dial for the chronograph at 3 o’clock. Continue reading
