Compatibility

These are generic aftermarket crystals sized by diameter — not made for a single brand. They are widely used as replacements across many vintage and modern watches. Confirmed compatible models from collector community sources include:

  • Seiko King Seiko 5626-7000, 5626-7111 — MD 300 (Ø30.0mm) used as aftermarket replacement

  • Seiko 6139 Chronograph series — including 6139-6000, 6139-6001, 6139-6002, 6139-6005, 6139-6007, 6139-6009, 6139-6010, 6139-6011, 6139-6012, 6139-6013, 6139-6015, 6139-6017, 6139-6019, 6139-6030

  • Seiko 7C43-6010 — MD 28mm variant noted as a good fit

  • Seiko LM Special — MD 285 (Ø28.5mm) reported as fitting well

  • General replacement for vintage Seiko, Citizen, Orient and many European dress watches with matching internal diameter

Always measure your watch's existing crystal or case seat diameter before selecting a size. A tolerance of ±0.1–0.3mm is common — some fitting adjustment may be needed.

Notes

  • Sternkreuz MD crystals feature a frosted bevel edge; original crystals on some models may have a polished bevel — this is a known difference

  • These are aftermarket mineral glass, not Seiko Hardlex or OEM crystals

  • Not the MDH (straight wall) variant — the MD series has a bevelled wall suited to a narrower diameter range

  • Sold individually — please select your required diameter

Durable for light to medium chewers - not heavy
Color: Green Cactus
obviously cute. not super durable - lasted a good minute but disintegrates fairly quickly and eventually nothing was left - having to high monitor with a big chewer. (10 mo Great Dane)

Unbelievable toy for aggressive chewers
Color: Green Cactus
Great toy for aggressive chewers! I'm not one to hand out 5 star reviews but this one I 100% believe in. I bought the first one in 2023 and just replaced it because it broke. Now this is not a played with every once in a while, this was played with daily as it is his favorite toy. Very few toys last long but this one has went beyond my expectations. Could not be happier.

Not Recommended!
Color: Green Cactus
Be aware that with major chewers it is not durable. My dog tour right through it and was eating pieces off of it. Thankfully we got the pieces back out of his mouth but definitely not for tough chewers. Also only lasted 2 days in decent condition and was only used on the occasion throughout the day.

Not strong lasting
Color: Green Cactus
Didn’t even last 3 hours in my house. Too rubbery and our frenchie mix was able to bite pieces off and was trying to eat them. Don’t recommend as a super chewer or consider it durable

Very durable!
Color: Pink Cactus
One of the few actually tough chew toys for dogs who tear apart toys in seconds! My dog loves this thing and has yet to break into the rubber!
