- Phong pushers are not gen spec - this means that if I want to swap for gen pushers later, they will not fit. Pushers holes are not easy to retap due to the very thin threading. I didn't know this until my watchmaker told me he can't do anything with gen P302 pushers So I will do the same operation on my 6265 later...
- Phong "MK0" pushers are only standard pushers reshaped and polished on the teeth. The number of the teeth and the global shape are not the same at all. To be honest, Phong "MK0" pushers just looks wrong. That is not something I can do considering all my other parts are gen. However, I have to say standard Phong pushers looks quite good. It's visually quite similar to the P302. I'll do a photo comparison later.
- I did have the opportunity to catch prototype "MK0" (P300) pushers in good conditions at a fair price (1,8K€), but I didn't pulled the trigger. It's maybe a mistake... I'll see later for this, it's not a hurry, P302 pushers looks good. I still don't know if it worth the cost to do this on a replica. That's a real question The other problem is I will feel stupid to have a service bezel (MKIV) with prototype pushers. It just don't make any sense. MKI bezel will be a must at this moment. Endless game if you ask me...
Quick correction: 6240 had prototype pushers MK0 (P300). From 1970 (6263/5 production begin) to 1975, it is MKI (P301). Then, from 1975 to the end of the production, MKII (P302) pushers are used.
Phong is doing a replication of MK0 pushers. At least, he tried
