How to order the right part
What we need from you
Set these in the boxes above when you order. Size only applies to some parts — see step 3:
About size: only temple arms come in different lengths, so a size box appears for them — it's the two-digit number after the colour code (e.g. 54□16 → size 54). Screws, décor and cases are one fit, so there's nothing to pick — that's normal, not a missing option.
Where to find your codes: printed on the inside of the temple arm — the model number (e.g. RB4165), the colour code (e.g. 601/71) and, for temples, the size. Not sure? Email us a photo and we'll confirm.
Fitting your new part
Some parts — like screws and end tips — are a simple job at home. For temple arms and décor, or if you'd rather not risk it, let our UK lab fit them for you.
Stock & delivery
In stock: if we hold your part in our lab, it's dispatched the same day when ordered before 3pm.
Not in stock: we order it directly from Italy (Luxottica), which takes 5–7 working days to arrive before we send it on. If you've chosen Next Day Delivery, it ships that way as soon as it reaches us.
For an exact quote and timescale on a specific part and colour, email our customer service team.
Why repair, not replace?
A single worn part shouldn't cost you a whole new pair. Replacing it keeps your Ray-Ban RB3789M out of landfill, saves you money, and keeps the frame you already know and love. It's what we've done since 1999.

Common questions
Are these genuine Ray-Ban parts?
Yes. Every part is authentic and ordered directly from Ray-Ban (Luxottica), made for your RB3789M — never an aftermarket copy. They're supplied in Ray-Ban packaging with a certificate of authenticity.
How do I order the right part?
Choose your part from the selector above, then add your colour code and size — all printed on the inside of your temple arm. Unsure? Email us a photo and we'll confirm the right part before you order.
Which parts can I order for my RB3789M?
Depending on the frame, you can order temple arms, temple screws, branded décor trim and a genuine case — whatever's available shows in the Replacement Part selector. If you need something you can't see, email us and we'll source it.
Do I need to choose a size?
Only for temple arms — they come in different lengths, so a size box appears for them (it's the two-digit number after the colour code, e.g. 54□16 means size 54). Screws, décor and cases are one fit, so no size is needed — if you don't see a size option, that's normal.
Can you fit the part for me?
Yes — choose “Sunglasses UK to fit” (+£10) at checkout and we'll email a Royal Mail returns label. Send your frame in and our UK lab will fit the part and post it back.
How quickly will it arrive?
If we hold your part in stock, it's dispatched the same day when ordered before 3pm. If not, we order it directly from Italy (Luxottica), which takes 5–7 working days to reach us before we send it on.
Can I cancel my order?
Because each part is a custom item ordered to your model and colour from Luxottica, orders can't be cancelled once placed. Please double-check your part, colour and size first, or email us and we'll confirm before you order.
