Looking for crystals [message #5456]

Looking for two crystals. I haven't taken the old ones out, so I have no measurements. I'm going with the case style numbers only to start with.

* 885/8 Model: Tank "Imperial 16"

* 370-821 Model: Curvex Evens or Model 801

I prefer the original glass crystals.

The Curvex has a good crystal now, but this is one of those extremely thick high crystals which I don't like and doubt was originally fitted to this model.

I will look to see what I have in the Curvex, but I can tell you that the Imperial Tank crystals are surprisingly difficult to find. I ended up ordering my last ones from W. S. McCaw, and they are a cylinder style, with slightly raised edges. The originals are flush fit, but sometimes you have to take what you can get.

I have several different styles of crystals for the 370-821 but I will need some measurements on the other . I understand you not wanting to remove the old ones yet, so even rough numbers would help me focus.

Thanks veritas123. Without removing the original crystal from the bezel of my Tank 885/8, I measured 25.2 x 20.0 mm. As Cary was mentioning the case has a flat bezel and the crystal is flush fit.

Appreciate if you can help me out.

Those helped. I think what you are looking for is a B&B X2495/200 or a Perfit C247/2-199. Neither of which I have. When you remove the crystal , let me know what the actual measurements are and I can look again.

Would you mind posting a picture of your Curvex Evans? I have a different style number down for that one. My notes show 370 662. If there is a second style number variant, I would sure like a picture.

I don't believe you watch is a Curvex Evans. I don't know what it is despite spending some time on it. HolbensFineWatches was nice enough to donate the photos for this post. The illustration is from "The 1950s" page 165. Is is the peaks on the sides of the case that was the tip off for me.

Thanks, you're 100% right Embarrassed

I checked Bruce Shawkey's Guide again and at least "Curvex 801" is right (page 105)

Thomas,

thanks to the forum you now know what you don't have: a Curvex Evans.
If you'd like to know the name of your fine watch: it is a Curvex Marcus.
It can be found on page 245 of Mikes 50s book and was advertised at least three times in May and December 1954.

I have a nice double facet crystal for that one. Matches the case style lines perfect.
