3717 crown size?

[boneventura]

Hi all,

I'd like to replace the crown and tube on my 3717 with gen. I see different sizes on the bay. Does anyone know the right one?

Thnx!

Uhmm.. no, i have no clue.

Sorry buddy, not very helpful.

My 3717's rep crown appears to be 6mm. Might want to check with concepta as he sells gen parts for IWC.

i thought the crown was pretty spot on, no?

mine isn't. It's not done very well.

same mine, the engraving is not very detailed

bad luck i guess

dont think is bad luck, the rep crowns cannot be compared to the gen in terms of detail.

[ryaku]

correct, but mine is particularly bad

correct, but mine is particularly bad

had the oportunity to measure both.

Dont have a digital caliper, so using a normal one i would say gen is about 5.9 - 6 mm and rep slightly smaller maybe around 5.8 - 5.9 mm

There is a quality difference between both and since the groves on the gen are more pronunced, it fells a bit bigger than the rep.

sorry for the bad quility pics

Please stop... i thought i was all set with my 3717 but now i'm reconsidering it.

Thats the problem with rep... there is always something we can improve...

[boneventura]

Ahh thank you Hugo! That's why I love this forum!

BTW: anyone who did get an answer form Concepta lately? He would be the obvious start of the quest...

@ Ryaku: mabe we can one of our 'quantum deals'
