Parts advice for Yema Superman II Worldtime 300M Quartz Diver Watch

Recommended Posts

Hi All,

I am new to this site. I have been collecting vintage watches for about 8 years. Recently, I've been attracted to vintage quartz, including a Chronosport Sea Quartz and this Yema Superman II Worldtime 300M Quartz Diver Watch. 

As you can see, it need a crown and a bezel lock. I contacted Yema, which no longer has parts for this 1990s model. The bezel lock will be very hard to find I imagine, but I think a crown is more doable. The original crown was unsigned, so an aftermarket crown with the same profile and specs should work.

Does anyone have any advice as to where I might look for an original crown and bezel look or, alternatively, an aftermarket crown?

Many thanks,

you might can find another brand to fit like Tag or some other brand for instance if can't find OEM, I can't see from the picture if you case tube has external or internal threads, most tubes are 2.5 mm diameter, there are a lot of generic case tube and crowns out on the market place, Borel, Star Time etc. they also carry different styles of locking buckles that should work but again no picture to see what is broken, I mean if it is just a pin well that is an easy fix...Happy New Year

    • These are the places where I oiled with HP 1300...  These are the places where I oiled with HP 1300...  I can see that the cannon pinion is moving as it should once I installed the pallet fork. I created a small video but was not able to upload it. It is a mov file type. I need now to source a GR4014X mainspring, a stop ever #9433 and both calendar disc as the days/dates are peeling out... This is the mido watch which holds the ETA Movement.... I just want to thanks all of you guys for your help, specially @eccentric59 who nailed it! So, I would consider this case as closed unless of course any question from any of you... Best regards Fernando     I could not download the file... I will tray to located. Many thanks. 
    • Thanks a lot everyone!  I'll update you as soon as a final decision has been made by my friend (and depending on her decision, what I may find inside). 
    • Thanks Marc, clearly I have a lot to learn about metallurgy. I’d expect the cutting of tool or spring steel to be a lot harder to cut into a precise shape- I expect I’d have to anneal it first? 
    • Unfortunately if you have used mild steel you will have little hope of hardening and tempering it, it simply doesn't contain enough carbon. You need to use a steel with a higher carbon content like tool steel or spring steel. One good source for this is engineers feeler gauges which can be picked up relatively inexpensively and provide a range of thicknesses of material. this will then harden and temper in pretty much the way you have described.
    • Thanks for this excellent tutorial and very fine illustrations @Jon! Really first class! 👍 I noticed that your image was a bit too small to read with ease, so here's a larger copy of it. I summarized @nickelsilver's method for adjusting beat errors to the following, but you can find all the info in the thread I linked to: “For everyday work, from the smallest ladies’ movements to marine chronometer, I set the balance with the cock on a bench block so the roller table is in a hole, balance on the block. Lift up the cock and move it over- not flipping it, just moving laterally, until I can see the slot in the hairspring collet, get in there and adjust (for tiny watches this is usually with an oiler, larger, a small screwdriver). Go back in the watch and check on the machine. I hold a balance arm of the rim with tweezers while moving the collet.”
