Anyone have an Omega Perpetual Calendar?

[andy1100xx]

As far as I'm aware Omega only seem to have produced a few perpetual calander's in the Louis Brandt range. Is this right? Either way they seem to be as rare as hens teeth...anybody got one?

[M4tt]

I don't know about the Brandt range but I have a Constellation 'Double Eagle'
perpetual. The thermocompensated movement is rated at +/- 20 seconds a year although mine runs at slightly less than half that - I suspect that this is closer to the norm.

The face is fantastic although the strap is possibly the worst Omega do.

Any specific questions?

Yeah, I noticed that some of the Connies were perpetual calendars but for some (bizarre) reason I thought all quartz watches were automatically perpetual calendars so this was just a marketing ploy. Now I realise this is obviously not the case. :roll:

BTW, I was having another look on the net last night and there was also a Japanese only Speedmaster perpetual calender back in 1991. Limited to 100 pieces :-p

Louis Brandt Collection 1984, calibre 716, 193 pieces, based on calibre 710-712 superflat automatics

Louis Brandt II Collection 1991, calibre 1116, 1118 and 1117, based on ETA 2890-9, with 245, 4 and 313 pieces (the 4 are skeletonized)

Louis Brandt IIs are the only Omega sold (that I know of) without a serial number in the traditional form, which is 8 digits after about 1945. Their serial numbers are two letters and three numbers.

There was a non-commericialized calibre 1113 -- don't know how many produced

The Speedy perpetual was Calibre 1160, per Omegamania catalog only 50 produced.

Yes, I have one -- and I really should take better photos

To be honest, the perpetual calender function is a bit of a red herring (especially in the UK where they don't allow for British Summer Time).
What is important is thermocompensation.

An average quartz movement is very badly affected by ambient temperature and thus cannot really be rated at more than about +/- 15 seconds a month.

Yes, I know that many SeMP owners can get far higher accuracy that this but the 1538 movement isn't compensated (just very carefully set up for the expected temperature range) so this is just a lucky side effect of our temperature controlled existence - take it on holiday somewhere hot or cold and things go wrong fast.

A thermocompensated movement can be far more accurate - the current technology leaders are Citizen and they have made watches rated as accurate to +/- 3 seconds a year and currently sell one rated to +/- 5 seconds a year. I have a similar one rated to +/- 10 seconds a year but it currently shows no deviation since Christmas.

I wouldn't be surprised if Omega moves all of their quartz over to thermocompensated - it shouldn't cost much more but gives a real USP over the vast majority of watches. It would fit their current market placement strategy rather well.

My X-33 is about - 5 second's a month..my black face SMP quartz is about + 3 second's a month. John Wilson. P. S. Nice Omega Hewy!

[M4tt]

I'm pretty sure the x33 is thermocompensated and could be returning better - is is a consistent gain or loss?

[Hewybaby]

Thanks, John!

I was beginning to think no one noticed I posted!

Hello,

I'm curious regarding the strap (bracelet). What don't you like about it?

Thanks.

Thanks for the info and the photos Hewybaby....that is one very classy watch :-p

According to the ETA docs, the movement in the X-33 is not thermocompensated. But it is a Flatline, which is their best line ('Thermoline' movements are also in the Flatline).
