Seagull ST 19 / Venus 175 Crown Wheel Core

Recommended Posts


Advice requested. 

One of the two screws for the Crown Wheel Core has, well, flow the coupe! I have a selection of generic screws from Esslinger, though I don't know if I can find a suitable replacement. CousinsUK  has the the Crown Wheel Core replacement, but I don't know if it includes the two screws.  If I look at the parts list it looks like the Crown Wheel Core is #423. Next I think the screw is part number 58281 (not sure though). If I can't find a replacement screw from my Esslinger collection, I need some advice:

1.) How can I match up PN 423 to the correct screw?

2.) Is PN 58281 the correct screw for PN 423 and if so how do you know this?

3.) If I order the replacement part from Cousinuk, how do I know if it comes with the two screws? https://www.cousinsuk.com/sku/details/venus-movement-parts/ven180423

4.) As a side note, can anyone recommend kit containing a selection of screws (in case I can't find a replacement in my current Essingler kit). 

I've included a picture of the part along with a parts list. Thanks in advance for any help that can be provided.

    • Think it's this one: https://www.aliexpress.com/item/1005001670367765.html?spm=a2g0o.productlist.main.3.2dc850b67RQSnK&algo_pvid=2f946012-60ff-49c9-b4a7-76e0eb3d45a7&algo_exp_id=2f946012-60ff-49c9-b4a7-76e0eb3d45a7-1&pdp_npi=3%40dis!GBP!39.89!30.32!!!!!%40211bf3f816853405030362238d07dd!12000029482496908!sea!UK!4321097666&curPageLogUid=n7ynCOcv20QC  
    • I don't have access to real-time or specific part numbers for Rolex watches. To obtain the accurate part number for the balance sock of a Rolex 1530, I recommend reaching out to an authorized Rolex service center or a qualified watchmaker. They will have the expertise and access to official Rolex parts databases to provide you with the correct information and assist you in finding the appropriate replacement part for your specific watch model. https://luxurysouq.com/product_brands/rolex-watches/
    • as far as I can tell for grand Seiko the only thing out there if you're lucky is the parts list. There appears to be no grand Seiko service manuals online at least that I've ever found. I do have a couple of links that talk about grand Seiko including the parts list.   https://mizeni.com/movements/seiko-5646 https://www.theseikoguy.com/grand-seiko-vintage/
    • Could you share the like from Amazon where you bought this? Thnx
    • Very informative thread! After reading through, I ordered a lamp from Amazon. Under $49 US (£39) tax shipping and delivered in 6 hours, yep! This one has 5 intensity levels and 5 color settings from 3200 to 6500. I use a binocular microscope and have the gooseneck lamp in case I need directional light. Don't mind the clutter of watches, those are usually moved off the bench when working on a watch. This really lights up the area nicely. The ring of leds on the binoculars is fairly cool when compared to the new lamp. I like it because once set it returns back to the setting when turned off and back on again.
