Dionigi,
On a practical level, while you may well be able to afford the purchase with respect to cash flow, 7-8% of net worth is too high for my taste. Emergency needs arise, tuitions inflate faster than everything else, and disability insurance is never high enough.
On an emotional level, , you might consider whether fulfillment of a "lifelong dream" in your 30s would prove a hard act to follow in your 40s, 50s, 60s, and beyond. Why not savor this particular expectation a bit longer? Lifetime achievement awards are best received after a lifetime of achievement.

You're talking about 7-8% of your net worth. I'm probably the biggest moron on this forum. Believe me or not but for me almost everything goes into this passion. As long as I can pay my bills every month I feel safe to spend the rest. 10K on my bank account or 10 K for that new watch I'm saving fo ? . For me it's a decission I make in 0.2 seconds. I'll go for the watch. Some members on this forum are very wealty others are middel class (like me). Some guys can buy a watch after a good business deal they made, for me (and a lot of others) it's a matter of saving. I don't have a huge collection and I do not have the tourbillons or minute repeaters but I am very happy with the ones I have ! When your grail is the 5078 I might compare it with my grail which I bought in 2006. My 5070R.
It took me years before i decided to buy this watch. Why ? Because for me that was a lot of money. I had to sell almost every other watch I had in my collection, a collection which started in in the early 1990's. When I do not include my house I can tell you that it was a lot more than 7-8% of my net worth at that time. A LOT MORE !
Am I nuts ? maybe. But you can't imagine how much pleasure I got from that purchase.
Besides, I do ALWAYS look at the secondhand value of the watches I would like to buy. Because there could always happen something that I need to sell one or more watches. I almost calculate in watches. When I need 4-5 K I won't take 5 K from my account, I would sell a Rolex sub LOL.
So yes, I only buy watches with a very good resale value. Or I buy second hand. The only problem I have is that there a some watches out there which I would love to own but I can't because they don't fit in my ' good resale value' rule. One example is the Journe Chronometre Souverain. I would love it.
So, do I need to make money on a purchase ? NO that is not my goal but on the other hand I won't buy it when I know I will loose a lot on it, simply because I can't afford it, and there is nothing wrong with that.
Concerning your MR, If you can afford the loss you'll make if you would ever sell it (15-20% ??) than go for it. If you think loosing 20% on that amount is way too much, than don't buy it.
That is ofcourse my own opinio, others might have a very different way of thinking


We have quite some things in common
I don't golf, - me neither
don't smoke, or drink fancy wines -- I stopped smoking 12 years ago and I never drink any alcohol
...so having a car is not really a major factor in mind. -- we have 2 but it ain't Porsches and my girlfriends car is for free, she got it with her job
I also do not have children nor am I married so that may lessen my "responsibility" load. -- I have a GF, we live together but children are not for us
I think your views reflect many of our fellows watch lovers. I think it is indeed a very practical view to adopt. We may go around collecting these beautiful pieces. But there will come a time where we will just reflect and say to ourselves why and if u are saddle with very expensive watches but with very limited resale values u are gonna be very disillusioned.. Going for the PP5078 is certainly a grail that many of us aspire. but how many of us really appreciate this and ask whether it is a practical watch to own.

this is a very difficult decision to make - because purchasing the MR now has considerable opportunity costs because of the very high price tag. the 5078 is in the $600k USD if I am not mistaken. So you forego what that $600k would have made had you instead invested over 15 years, plus the potential loss should the 5078 ever depreciate in a slowing economy.
But, as you say it would represent 7-8% of your net worth- so that one metric it seems a no brainer to buy one.
if you doint mind me asking,have you been approved for a Patek MR via the application process ? IF so how many pateks bought did that require ?
but I can make as many arguments in favor of this purchase as against it. I have wanted a Patek MR for years but have money tied too tightly into investments for me to divest and buy one. If you are like me you probably want a small and impassioned push in favor of getting one, perhaps from an enthusiastic owner who has perspective on ownership. but then there is the sensible side, which counters with many arguments.
1. the Patek MR could lose value. Especially over time. Mechanical marvels were not always so sought after and valued, were they ? ie the Quartz revolution made mechanical watches seem obsolete for a time. The idea of paying 6-7 figures for a watch that could strike the hours and quarter hours and minutes was probably ludicrous when you could get a quartz watch, or casio, for as little as $50 that could do for more functions and alarm and temperature etc etc. The resurgence of the MR and mechanicals came when the US economy surged in wealth. Could the reverse happen, as it appears, heading into perhaps world recession, where mechanicals costing 6 figures be seen in very bad taste, and their prices drop to more down to earth levels ?
2. The Patek brand is lusted after partly because of marketing wizardry, not so much technological reasons. Many brands like Vacheron and JLC also produce as complicated and wonderful pieces technically, but arent quite recognized in the same league. I think there isnt a lot of difference in the major manufacturers as far as the wonderful limited pieces they can produce. What makes a Patek 5004 ( split second and perpetual calendar ) objectively worth $200k more than an IWC da vinci perpetual rattrapante, which has the same functions and thus is technically on par with Patek, but a factor of about seven times cheaper ?
3. wanting something because of exclusivity, and because a lot of other people want it, tends to lose lustre after a while of achieving it. Not saying this is part of your reasoning, but something I grapple with in coming to grips with purchasing something like this.
1. You can afford a 5078
2. If you feel better having the watch and less cash, buy it but
3. If you feel better having a bit more cash and no 5078, don't buy it.
I would buy - without any hesitatation but that's me. Hope to see some pictures soon.
Best, Kari
have 1 5970p
but used the sale of other watches (incl profit on theire value) to purchase
also No mortgage, this was my priority in life to clear...hence the 70 hour weeks
then finally the 5970p have to have no impact or sacrifice for my family
and ..... it is relatively depreciation proof
I think personal circumstances are very important before spending this much money
if you are millionaire, and very liquid, why not...go for it
as for debt..
a mortgage is one thing, but borrowing money for "luxuries" ... no, I dont think so, not in my book anyway
best of luck
