I always try to go with the ETA movements as they are usually more true to gen ie: smooth sweep, date fonts etc. and then just let them run till they show signs of needing service then just replace them. Works out at around the same cost as service give or take a few dollars...plus gen hands etc. are compatible too!
LOL states in specs...
Weight - Within grams of the original timepiece...doesen't say how many though, could be within 100grams!
Top tip...never buy a watch from replica sites that show pictures of gens.
Have quite a lot of ink and sometimes get remarks from people some good, some not so good.
More often get remarks about whatever watch I'm wearing at the time.
Congrats on your 5000th post lanikai
If it's the DG2813 asian 21J movement then it should keep excellent time and prove to be a workhorse...not as smooth on the sweep as the clone I'm afraid but not too noticable when "on the wrist".
