My favorite 2024 is the Prospex Limited Edition 1965 Recreation European Exclusive in Gradation Island Blue. The dial is stunning and the contrast when on a white strap is to die for. I will get my hands on one from amzwatch

let's go!

[@4211Rob]

Fantastic learning experience! Thank you!

[@arthur-loh]

thank you!

As a broke boy and actual enthusiast who wants watch’s prices to crater, MAMACOO is a good choice.

[@debanjansengupta3802]

Its nice.. Please do one with day and date quartz seiko watch.

[@arthur-loh]

Thanks! I would love to build a quartz seiko watch. However i can’t seem to find any quartz seiko day date movement. Closest i can find is a VK63 seiko movement, for a Daytona style chronograph watch. I would love to try building that one day!

You don't need to push the stem release lever to install the stem...only to remove it.

[@arthur-loh]

i agree. but i think it's a good practise to push down the lever when installing the stem. on one of my build, i installed the stem without pushing the lever and i broke the keyless work (which i need to open the movement to fix it).

[@mantra1481]

Could you put in the description what each part is and a link to them?

[@HeisenbergDegg]

Это слишко сложно. Проси, чтоб сразу отправил тебе эти часы

[@arthur-loh]

hi! yes. i have added the link in the description. feel free to check back once the link is working.

[@mantra1481]

@@arthur-loh thank you

[@arthur-loh]

Hi guys! I just added the link to all my parts and tools used in this video in the video description.
Sorry it took a while for me to prepare as CZcams requires some verification to have the link activated. So feel free to check back the video description when the link is active!
Thanks for the likes, comment and support! I truly appreciate it!

[@AdebarLonge]

All dat MAMACOO watches sssssoooooooo gorgeous！

[@arthur-loh]

thank you!! appreciate that

[@subhradeepbhaduriadi5116]

nice work

[@arthur-loh]

Thanks! 😊

[@AdamF20]

Good job!
Did you use the 36mm or the 39mm case?

[@arthur-loh]

i used the 39mm case. fits perfectly for my wrist.

[@rc01980]

good video!

[@arthur-loh]

thank you!

[@oo.c.o]

cool idea and great design 😁👍
but you made a mistake
- you bend all the clock hands ... up - which, after a slight impact, may cause them to get stuck! ... & ultimately it doesn't look nice - if someone looks some carefully at the watch. 🥺

[@arthur-loh]

Thanks for the tips!

[@purva609]

what mm was the case

[@arthur-loh]

it was a 40mm case

[@joller79]

links dont work in descripåtion, but the case looks like the Neiton one, correct?? and you need to trim the crown stem just a tiny bit more..

[@arthur-loh]

Hi! sorry I am very new to CZcams. apparently i need to perform verification for the link to work, which i have just done. Feel free to check back the video's description for the working link! thanks for reminding!

[@arthur-loh]

And yes! you are right. it's a Neiton watch case and bracelet combo

[@jedleary5819]

Bro the stem is too long the crown didn’t screw right into the case. You need to measure the front of the threat to the inside of the crown and cut that measurement. You didn’t cut enough

[@arthur-loh]

hey thanks for the comment. yes you are absolutely right. i later on realize it and recut the stem to make it fit properly

[@cashnivek]

Why do you say 4 Minutes Off is ok?

[@arthur-loh]

yes, 4 minutes off is ok for me, personally. i would redo the hands if it's more than 5 minutes off. otherwise, i'm satisfied.
but feel free to remove the hand using a hand remover and redo the hands if you feel 4 minutes off is not good enough.

[@serdarayturk1209]

Very nice job. Next might be 36mmm explorer.

[@arthur-loh]

Possibly!
