Recommended Posts

Posted

Contemplating another project (I really need psychiatric help!!) maybe a Tudor Big crown or a 6538. i was wondering about the crowns, it looks like there are several on the market, Yuki,NDT, maybe others. Who has the best, most accurate crown?

I bought this and I am quite happy with it (tube and crown):

Brevet Crown

PS: I offered $95 and got it

+1 . I followed Donerix's advice and picked one up for USD100 delivered to Australia.

Looks pretty good

Does anybody know what size tap to use for this crown?

Boy, you sure have to hope it's the 3.0mm x .35 tap which is standard for all of the 6mm and 7mm tubes.

I was just goin to post a request for a new Brevet crown and tube But this post saved me the trouble my 6538 brevet crown and tube is screwed (please excuse the pun! i was wondering from where to get a replacement too . i saw somewhere some for sale for 30 usd but cant remember where ,i cant imagine that at that price they would be any good im a bit [censored] that after a year of owning my 6538 i have to replace my crown and tube but there you go! hope i can find a good one for a lot less than the 280usd iv been quoted

just been on there they quoted me 37usd for shipping to my country photos look good 95 usd seems reasonable.

There's no way that the tube for this thing is going to be the same diameter as a standard 7030.

The stem is the usual tap 10 size... And look how big the barrel is around the base for the stem.

Compare to a 7mm:

Granted, the pic is of an aftermarket 702, the sizes are the same as gen...

I will go and measure mine now ....

3.95mm diameter and 3.5mm for 10 rings of the thread.

So I am assuming you need a 4.0mm 0.35 tap

Experts can you please confirm that and maybe also tell us:

WHERE WE CAN BUY IT :)

Went tap hunting today and found the 3mmx.35 and the 4mmx.35 (for the 8mm crown, I took it with me and had them measure it),

I found them at Dewitt Tools, 6550 NW 72nd Avenue, Miami, 305-8881450.
