为回答这个问题我特意查看了一些国外的手表论坛，我只有一款万国没有真力时，即便有一块真力时我也不能就他俩的对比看作是两个品牌的对比以偏概全，而且国内同时拥有这两个品牌手表并出来评论的更是寥寥无几，所以我就查看国外的手表论坛。以下是我对论坛评论的归纳和总结。
单纯就这两个品牌而言，基本相当。但更多表友推崇真力时特别是2000年左右出产的（
the EP academy 月相表, or even the Dunhill el primero）普遍认为真力时手表用的是自家机芯，产品质量稳定，走时精准。性价比高。可见原文（Depends on which watches you are comparing. You may find a better movement for less outlay in a zenith but you may not like the way the watch looks. As alluded to above a c.2000 Zenith like the EP academy moonphase, or even the Dunhill el primero, offers rarity and quality movements but they both look like rejected Tag designs. Their time will come though...no doubt.）配图（真力时 EP academy和Dunhill el primero)
而万国多使用ETA机芯进行改造打磨，近几年万国的质量相对较差，原文是（You will be paying a lot more cash for a decent IWC than either of the above but you won't get anything as interesting inside.Can't really make a sweeping statement about brand mechanical quality though...because each watch is different and they change over the years.）价格虚高，性价比低。他们认为手表外观设计万国优于真力时，同时肯定真力时外观也在不断的进步。当然也有人认为万国3536 Aquatimer，或IWC Deep下配图(万国3536 Aquatimer，和IWC Deep）
看过他们的评论我个人认为，两个品牌都有让人喜爱的表款。所以在你购买时你要想清楚你究竟需要什么，如何在众多表款中选着你最中意的，恐怕你还需作更多的功课。
