The Longines L888.4 is a top grade ETA 2824 with special decoration and has been adjusted to chronometer specs, adjusted in five positions and achieving an average daily rate of +/-4 seconds with a maximum daily variation of +/-15 seconds to receive COSC certification. The top grade has better components than the standard or elaborate grade. The top grade becomes COSC when it receives the adjustment and certification.
This movement is a workhorse, is very reliable, very common, and is used in a multitude of watches. It is seen in high-end and budget watches and has been around for many years.
I would say that any independent watchmaker you go to has serviced many of these movements, and you won't have any trouble getting it serviced.
The top grade and the COSC L888.4 feature better Shock protection - Incabloc Novodiac, and a better Nivaflex NO mainspring. It is adjusted to five positions. The top grade can recieve COSC certification like your L888.4. There are no plastic movement parts but variations of the movement may be changed by the watch company using it. It is very doubtful that Longines added any plastic parts in the L888.4 to answer your question.
The main difference between the Longines calibers L888 and L888.4 is that the L888.4 is a COSC-certified chronometer and includes a silicon balance spring. The L888 movement is not necessarily COSC-certified and may not have the silicon balance spring.
You will have no problem finding a watchmaker to service it. Just make sure he will adjust the watch within the tolarances mentioned abobe. May I ask where you are located in case any members are able to reccomend a watchmaker in your area if you don't already have a go to guy. Also we love photos. Please attach a watch pic if you are able.
