Customer Reviews
Bought last July. Still ticking, still classy. Great quality for the price.
I Love my new watch
The seller went the extra mile and gave me a bezel wich suited my purpose better!
Time flies — it’s already been a year since I bought this watch and I love it even more now.
Got this watch from here a year ago. Excellent build, solid performance, and beautiful design.



Clearly this is a true omega.


Beautiful and high quality mod watch. Better than expected and such great customer service and communication. Thank you for making this a pleasant purchasing experience.



This is a superb watch, I didn't want a Rolex clone but instead decided to go with the Seiko mod. I'm glad I did, the quality on this build is amazing, and Josh the owner was very helpful in answering my questions. You can't beat this for the $, I will be purchasing another one in the not too distant future.
Purchased a year ago and I’m amazed at the quality. Sleek, reliable, and budget-friendly.

Can’t believe how well this watch has held up after 12 months. Looks way more expensive than it is!

I’ve had this watch for a year now and it’s exceeded expectations. Affordable luxury!

I’ve had luxury watches that don’t last this long. Got this one from here a year ago — still going strong!
Very well put together, solid feel
The watch lived up to my expectation! I got i jubilee and that made the watch even better!



A year later and this watch still keeps perfect time. Super impressed for the price.

I was deciding between a submariner mod from Josh and one from another website, when I compared reviews and saw that everyone says Josh?s (thelumelab) has a more solid feel to the watch. I made the right choice. This watch looks and feels great
Stylish and reliable. I've worn this watch every week for the past year and it’s still like new.
Had it a week so far and it is my favorite watch. Quality seems great. Will be buying again if I need to scratch the Rolex itch. Wanted a solid case back to engrave with my unit and Josh was very helpful. Very timely shipping and packaging was solid. Thanks buddy.
This watch was a steal! Been a year and I’ve had zero problems with it.

I honestly didn’t expect it to last this long, but here we are — a year later and it’s perfect.
Nice watch it’s a good watch niggah
Picked this watch up from this shop a year back. Looks elegant and works great even now.


Been using this watch daily for 12 months — no scratches, no issues, just perfect.



If you're on the fence — just get it. I did a year ago and I wear it all the time.



I bought this watch from this store a year ago and it's still working perfectly. Great value and looks stunning!


Bought my first mod watch as a birthday present to myself and have had it for a couple of weeks now. It?s a beautiful watch and Josh was very helpful and personable. Highly recommend.



As others have said - super pieces, superb service.



Anyone can leave a review regardless of purchase, how accurate could the reviews really be?
Beautiful watch! Shipped quickly! Very happy with the purchase thank you!

Amazing custom buy with confidence
Great seller. Would absolutely purchase another watch from him.

Looks amazing ,well made , great service, this is my second watch from Josh I will be buying another
Great quality watch and some of the best customer service I've ever received. If you're thinking about just buy it
One of the best purchases I made last year. The watch still works flawlessly.

Bought it 1 year ago — still ticking strong and looks brand new. Definitely worth it.

Very good product. Nicely made and with a good haptic! Would buy again.
I wear this watch almost every day and it's never failed me. Got it from this shop last year — no regrets!
I've had my watch for about a week now and I'm in love. Very happy with the quality and look of this watch. It's been hard to take off and I haven't worn another watch since I received this one. Thank you very much.

Shipped super fast! Item is great, would defiantly recommend. 5 Stars.
It’s been a year since I purchased this watch and I still get compliments. Affordable and super stylish!
