New 42mm Hybrid Movement Diver's Watch Case

It has been a month since the release of the 38mm Hybrid Movement Diver's Watch Case.

Here comes the big brother, the SKX007 version, 42mm. Same as the 38mm version, this is a one of a kind watch case in the market that can fit both Japanese Seiko NH movements (NH35, NH36, NH37, NH38, NH39, NH70, NH71) and Swiss GMT movements (ETA2893 and SW330).

This watch case design will undoubtedly opens up a myriad of breathtaking opportunities for customisations. This is also one of the first aftermarket case designed to fit two structurally different movements of different origins.

FREQUENTLY ASKED QUESTIONS

Does this watch case fit SKX007 aftermarket parts?
Yes, only to our own SKX007 aftermarket parts since we have tested it.
Is caseback for NH and ETA2893/SW330 GMT movements interchangeable?
No, casebacks are NOT interchangeable. GMT movement is significantly smaller and slimmer than NH movement, its caseback is therefore significantly thinner than NH caseback.

**Using GMT caseback on a case fitted with NH movement will inevitably damage the NH movement! Please ensure that you select the proper caseback for its respective movement.
How is NH movement fitted into the watch case?
NH movements can be fitted into the watch case directly without any addition GMT movement spacer. A unique NH caseback is required to secure and close up the watch case.
How is ETA2893/SW330 GMT movement fitted into the watch case?
A unique GMT movement spacer (gold colour in the photos) is required to encase the GMT movement inside the watch case. Thereafter, another unique caseback specifically for this movement is require to secure and close up the watch case.
I have bought the NH movement version of this case. But I want to fit an ETA2893/SW330 GMT movement into it now.
Too easy. You just need to purchase the GMT movement caseback and spacer separately, which you can select on this product page. That would allow you to fit GMT movement. Likewise, you can purchase NH movement caseback separately.
Will your dial collections fit ETA2893/SW330 GMT movement?
Yes and no. No because the dial legs are designed for NH movements. So current dial collections with NH dial legs will not fit into GMT movement. Furthermore, the date windows do not align between both movements. On the bright side, yes, it can still fit (only no date dials), but requires you to remove all the dial legs and manually align and adhere with adhesive (e.g. double-sided tape). We will release GMT movement-specific dials next year.
Do you have ETA2893 or Sellita SW330 movement?
Coming next year.
Do you have ETA2893 or SW330 movement hands?
Coming next year.
Do you have bracelets for this watch case?
We will be releasing our own selections of bracelet for our watch case in first half of 2021. Meanwhile, this case has lugs designed exactly like SKX007. Hence, OEM SKX007 bracelets can fit this watch case. We can only guarantee OEM SKX007 bracelets will fit. For aftermarket bracelets for SKX007, it may or may not fit. You will have to check with the respective retailer you purchased from.
Hands installation on ETA2893/SW330 movement is more difficult than NH movements.
Correct. Compared to NH movement, it is extremely difficult. ETA2893 and Sellita SW330 movements are smaller, slimmer and have about 40% lesser space between the hands as compared to NH movements. What's more, within the 40% lesser space, you need to fit 4 hands (hour, minute, second, GMT) instead of 3 hands (hour, minute, second). This makes your margin of error very tight when it comes to hands installation. Just take hour and minute hands spacing for example; On NH movement, there is 0.6mm space, while on ETA2893/SW330, there is 0.4mm space.

**Unless you are an extremely experienced modder or a certified professional watchmaker, we do not recommend any individual to work with GMT movements.
