Zenith stainless steel winding crowns different sizes and logos styles to choose from.
Please read the description below before you buy. It should answer most questions.
These are vintage Zenith wristwatch winding crowns and there is are mix of dust resistant and waterproof styles to choose from. Dust resistant crowns are the style with the spring loaded plunger that rides against the case when installed. Please be aware that the waterproof crowns with the rubber O rings have vintage rubber O rings in them so the O ring may be hard to very soft. No guarantee of water resistance is given or implied. These crowns are only offered as replacements to keep the period look of your vintage Zenith wristwatch.
Please note that crows #4 and #20 have two different logos to choose from. I have these listed as "A" and "B" versions in the pics and in the drop down list above. Be sure of your choice of crown before you pay with regard to either of these crowns. Also crown #4A and #4B both come with a case tube.
I have three crowns in each pic so you can see what it looks like from every angle. You only get one crown per purchase. If you want more than one just change the quantity when you select the crown you want.
I also have noted the dimensions in each pic of the crowns so you can measure yours and pick the correct one from my list.
I have noted millimeter dimensions of:
1.Outer Diameter
2.Height with tube(this measurement is for crowns that have the threaded tube for the stem that protrudes past the bottom of the crown)
3.Thick(height of crown itself excluding the threaded tube)
4.Tube(outer diameter of case tube diameter that the crown fits. This measurement applies to water proof crowns only)
5.tap size(diameter of the stem that will thread into the crown. Please note I have some crowns that have two tap sizes listed in the pics. Reason for this is that .90mm and 1mm are very close and will typically screw onto a stem that has 1mm or .90mm diameter. Obviously it will be a little loose on a .90mm, but will tighten down and stay on the stem typically speaking)
