Oils for NH35

The technical guide for the NH35 specifies MO-3 and MO-4 oils. I have read that these are comparable to a couple of Seiko oils. Does anyone know if they are comparable to any Moebius oils, and is it okay to substitute the Moebius oils?

Another thing - the technical differentiates between “normal quantity” of oil and “sufficient quantity” of oil. Now, aside from the obvious poor choice of language (shouldn’t the normal quantity be sufficient and vice versa), what exactly is the difference?  I suppose I could go through the parts that get a sufficient quantity to try and determine if they are parts that typically get more (or less) oil than others, but what exactly do they mean?

MO-3 is comparable to Moebius HP1300 and to be honest MO-4 can be the same, but I use Moebius 9504 in place of the MO-4 which is for high friction parts, but as I said you can use HP 1300 instead. There is a big difference in viscosity of these two lubricants, as Hp1300 is 1300 centistokes which is pretty thick and 9504 is only 305 centistokes, but I find it better in the situation for high friction parts.

If you ask 10 watchmakers which lubricants they use, you'll get 15 answers!

Thanks. I figured the MO-3 was similar to HP-1300, but wasn’t sure about the MO-4.

Don't take any service manual as gospel. Just put the correct amount of lubricant where it is meant to be and all will be fine

If you ask 10 watchmakers what is "correct", how many answers will you get? 🤣

      AS 1475 REFURBISH (Recalled to life)

      By mikepilk · Posted

      I've just finished refurbishing a Memostar Alarm with AS 1931 movement (same as 1945 but with date and running at 21600). I was also surprised how many parts are available at Cousins. Like you, I was missing the alarm stem (Cousins stock them) and I needed new crowns. It's a nice simple movement for an alarm, easier to service than a Seiko Bell-Matic. BTW I made a note in my Servicing spreadsheet: "Pull out winding stem before removal".  It may have just been wear on my movement, but I found that the yoke could move out of the clutch if the stem was removed in the normal position (like some ETAs).  You might find this interesting

      AS 1475 REFURBISH (Recalled to life)

      I picked up this alarm watch at a flea market several months ago and recently decided to investigate.  I am not finished, but well on my way. As you can see, there was significant water damage.  Running these parts through my L&R cleaner was not enough to clean them, so I did manual cleaning with one-dip and cotton swab (the dense pointed kind).  The wig-wag was stubborn--the two gears would not release from the plate.  I soaked it in Kroil overnight and that did the trick. There was some rust on the balance staff, but not actually on the pivots themselves.  Nevertheless, I chucked it a step-chuck on my lathe and burnished the pivots. The watch is running and I have confirmed that the alarm drive train is functioning.  Since I am missing a stem for the alarm, I have not done the final assemble of the alarm components.  Surprisingly, there are lots of parts available for this movement on Cousins.  I will probably get a couple of stems and maybe some other parts that I deem necessary. The watch is running at weak amplitude (about 190) and shows some poising issues.  I will work on that. The last two pictures are after partial reassembly.

      Exactly!  It may not really be a joke, but the actual truth.

      The movement is placed on the base and the centre screw is raised until it contacts and supports the centre pinion, thus stopping the centre pinion from sinking in when the second hand is pressed on.
