剛剛IWC總部回文，如下。只有三種情形會更換龍頭，
一、龍頭嚴重受損
二、龍頭防水有問題
三、顧客主動要求更換
如果龍頭防水有問題而堅持不更換，也是可以的，只是自己要注意。
如果顧客堅持，他們也可以把換下的龍頭寄回當做是禮物，只是顧客要提前聲明。
不知道各位對這樣的回答滿意嗎？我覺得還OK耶∼
Dear Mr. Lee,
thank you for your email. I understand your hesitation and thoughts about this issue. I can clearly read your frustration from your email. With my following answer, I hope to provide you with some clarification:
The fish crowns are not produced anymore and are replaced by the new "probus scafusia" crown, which fits the old stamp from IWC perfectly. The "probus scafusia" crown consists of the same high standing quality as the fish crown. The crown will be exchange however only for the following reasons:
1. if the crown is badly damaged
2. if there is an issue with the waterproofness
3. if the client wishes to do so
The new watches which we produce, all have the "probus scafusia" crown.
If you would like to keep the fish crown, we might not be able to guarantee waterproofness of your watch. If you find yourself comfortable with this, the crown would not be exchanged. If we exchange the crown, we can also send the fish crown back to you, as kind of a "souvenir" should you request that. However, if you would have this wish please advice the local IWC dealers in case you would like to send in your watch. The dealers of IWC should be aware of this issue.
I hope that I was able to help you with your request and remain at your disposal should you require any furhter assistance.
Best regards
Lorenz Peyer
